Today's Colloquium:  3:30 p.m.  Meinel 307

 

Dan Stancil of Carnegie Mellon University will present Optical Nanocircuits Based on Microwave Analogies.   Masud Mansuripur is the host. 

 

Abstract:  There is now considerable interest in the fabrication of optical nanostructures for applications such as optical data storage, microscopy, and communications. In contrast with conventional integrated optics based on dielectric structures, metals are of particular interest owing to the potential for confining optical energy over regions as small as a few tens of nanometers. However, materials approximating “perfect conductors” do not exist at optical wave lengths, and surface Plasmon phenomena often lead to quite unexpected behavior.  In this talk we will examine the behavior of metallic two-conductor transmission lines, rectangular waveguides, and ridge waveguides at optical wavelengths. Procedures for applying Plasmon corrections to the classical microwave relations will be discussed, as a step toward the development of design procedures for optical analogues to microwave circuits. Applications will also be discussed, including the realization of sub-wavelength optical spots for optical data storage.

 

Bio:  Daniel D. Stancil is Professor of Electrical and Computer Engineering at Carnegie Mellon University. He received a B.S. in Electrical Engineering from Tennessee Technological University in 1976, and the S.M., E.E. and Ph.D. degrees from the Massachusetts Institute of Technology in 1978, 1979, and 1981, respectively. Prior to coming to CMU in 1986, he was an Assistant Professor of Electrical and Computer Engineering at North Carolina State University. At CMU he has served as Associate Department Head and as Associate Dean for Academic Affairs in the College of Engineering, as well as Thrust Leader for Optical Data Storage in the Data Storage Systems Center. He was a leader in the development of the CMU ECE department's Virtual Laboratory which was a finalist for a 1996 Smithsonian Computerworld Award. Electro-optics technology that he co-developed was recognized with an IR 100 Award and a Photonics Circle of Excellence Award in 1998. Dr. Stancil is a Fellow of the Institute of Electrical and Electronics Engineers, and a past-president of the IEEE Magnetics Society. His research interests include wireless communications, antennas, and applied optics.

 


 

Special Presentation:  April 4, 9:00 a.m. Meinel 821

 

Please note:  This is a date and time change.

 

Andrew Berglund, National Institute of Standards and Technology, Center for Nanoscale Science and Technology and OSC Biophotonics Faculty Candidate will present Closing the Loop with Single Photons: Feedback Control for Single-Molecule Biophysics.

 

Abstract:  Recent advances in single-molecule fluorescence spectroscopy have enabled high resolution studies of single-molecule conformational changes and chemical dynamics and promise to shed new light on open problems in single-molecule biomechanics. However, the scarcity of fluorescence photons limits the spatial and temporal resolution of many experimental techniques. In this talk, I will introduce active feedback control for monitoring the dynamics of freely-diffusing fluorescent particles with temporal resolution spanning from nanoseconds to seconds. Applications of this technique will have a broad impact on single-molecule biophysics, for example in studying fast sequence-dependent DNA mechanics and the "protein folding speed limit."

Special Presentation:  April 8, 3:30 p.m. Meinel 821

 

Leilei Peng, Wellman Center for Photomedicine, Massachusetts General Hospital and OSC Biophotonics Faculty Candidate, will present Multiplexing Biosensing and Imaging With Optical Interferometry.   

 

Abstract:  The biggest challenge in biosensing and imaging is to detect and image thousands of bimolecules simultaneously.  This talk will discuss two interferometric methods that address the sensing and imaging challenge respectively. The first method, the Adaptive BioCD is an assay technique for detecting thousands of proteins. The second method, the Simultaneous Fluorescence Lifetime Excitation and Emission (SFLEE) provides a platform for dense multiplex image of fluorescence probes.

 

(1) Adaptive BioCD: biosensing with adaptive spinning-disc interferometry. Adaptive spinning-disc interferometry measures surface profiles of a thin biolayer with sub-nanometer longitudinal resolution. High-speed phase modulation in the signal beam arising from the moving surface height profile on the spinning disc is detected via dynamic two-wave mixing with a photorefractive quantum-well device. Biosensing of immobilized antibody monolayers was performed in both transmission and reflection modes. Reflection-mode detection enhances the biosensing sensitivity to one-twentieth of a protein monolayer, and is capable of creating a topographic map of the protein layer.

 

(2) Simultaneous Fluorescence Lifetime Excitation and Emission (SFLEE) measurements by Fourier transform spectroscopy.  The SFLEE technology provides the comprehensive, multidimensional characterization of fluorescence that will enable dense molecular multiplex microscopy. It utilizes Fourier transform spectroscopy to measure intensity and lifetime excitation-emission matrices in a single instrument. The instrument incorporates two primary Michelson interferometers: one interferometer modulates the broadband illumination source with a series of wavelength-dependent frequencies while the other interferometer measures the autocorrelation of the fluorescence emission spectra. SFLEE demonstrated: (1) fluorescence energy transfer measurements by intensity EEM, and (2) hyperspectral global analysis from a mixture of fluorophores, which allowed fluorophores being distinguished by both lifetime and intensity EEMs.

3rd International Workshop on Fisher Information:  April 7 through 11, Meinel 701

 

Exploratory Mining of Scientific Data Using Fisher Information:

With Applications to  Physics, Statistics, Pattern Recognition, Imaging, Finance,

Medical Research, Engineering,  and Philosophy

 

Sponsored by The University of Arizona College of Optical Sciences and Department of Radiology

 

From Roy Frieden.  The Workshop participants are all involved in research using Fisher Information from around the world.  In addition to workshops, public lectures will be open to all.  Conference themes on Fisher Information include physics, optics, statistics, coding, information theory, biological growth, cancer research, economics, cosmology, philosophy of science.

 

OSC students and faculty members are specifically invited to attend the lectures 

 

International Organizing Committee:

  • Professor Roy Frieden, University of Arizona, U.S.A.

  • Professor Sumiyoshi Abe, University of Tsukuba, Japan

  • Dr. H. Cabezas, U.S. Environmental Protection Agency, U.S.A.

  • Professor A. Plastino,  Argentine National Research Centre, Argentina

  • Professor Bernard Soffer, University of California at Los Angeles, U.S.A.

Monday 9:00 a.m.  B.R. Frieden and B.H. Soffer.  Title: The De Broglie-Fourier amplitude representation from EPI.  Abstract: The De Broglie wave hypothesis supplies the usual foundation for quantum mechanics.  Most generally, it states that the wave amplitude psi(x) at a position x is the Fourier transform of its conjugate wave amplitude phi(p) over momentum values p.  This relation seems always to be assumed. We show that, in fact, it derives simply.  This is by application of EPI to the scattering of a classical particle by a planar amplitude distribution (analogously, of a photon by the exit aperture of a lens system).  The key to the derivation is a scenario of unknown initial conditions for the particle, and a premise that the particle’s positional Fisher informationis conserved from the scattering plane to the image plane.

 

Monday 1:00 p.m.  Ray Hawkins.  Title: Fisher information and the risk-neutral densities of mortgage options.  Abstract: FI has proved quite effective in recovering the probability densities embedded in option prices.  The importance of FI in this type of analysis is particularly important in situations where there observations are limited.  In this talk I will discuss the use of FI to analyze mortgage options:  options with limited observations and with implied densities that differ significantly from the typical normal and lognormal densities of equity and bond options.

 

Tuesday 9:00 a.m.  R.C. Venkatesan.  Title: Information Security using a Fisher Game.  Abstract: A self-consistent formulation to secure covert information is presented.  The approach uses unitary projections into the ill-conditioned eigenstructures of multiple probability distributions that are incompletely observed. The multiple statistical distributions are the solutions to a time independent Schroedinger-like equation, corresponding to different energy states.  The process of inference is accomplished using a semi-supervised learning paradigm.   The "dynamics" of the Fisher game are compared with those of an equivalent nonextensive thermostatistics (NET) Fisher game.  The security provided to covert information by the "regular" Fisher information model is compared with that provided by the NET Fisher information model.

 

Tuesday 1:00 p.m.  Y. Shastri, U. Diwekar and H. Cabezas.  Title: Sustainable System Management with Fisher Information based Objectives.  Abstract: This work explores sustainable ecosystem management using systems theory based approaches such as dynamic optimization and optimal control.  Fisher information, proposed as a sustainability measure of natural dynamic systems, is used to formulate appropriate mathematical objectives for the management problems. Two different integrated food-web models with varying degree of economic details are analyzed using this approach. The results put forth interesting qualitative as well as quantitative guidelines for policy development, while overall highlight the role of system theory and information theory in sustainable management.

 

Wednesday 9:00 a.m.  S. Ames.  Title: Measurement interaction as the basis for EPI.  Abstract: I believe that measurement interaction (MI) is vital to the understanding of how Fisher information arises in physics. I will discuss some interesting properties of the MI, especially in its predilection to produce general loss (or, at least, no gain) of information.  Interestingly, a no-loss scenario arises out of three different forms of the MI.

 

Wednesday 1:00 p.m.  H. Cabezas, A. Karunanithi and A. Garmestani.  Title: Fisher information, sustainability, development, and political instability.  Abstract: Fisher information is a measure of order inherent in the time series data of any dynamic system.  We have computed the Fisher information for nation-states, using the data from 1960 to 1997 from the State Instability Task Force.  We find that nation-states fall into two categories: one with a low Fisher information and many political upheavals; and another with high Fisher information and very few political upheavals.  Further, we find that as nation-states evolve from an underdeveloped to a fully developed state, they traverse a phase of low Fisher information and great instability.

 

Thursday 9:00 a.m.  K.R. Narayanan.  Title: On the Thermodynamic Temperature of a General Distribution (and Its Relationship to Fisher Information).  Abstract: The concept of temperature is one of the key ideas in describing the thermodynamical properties of a physical system. In classical statistical mechanics of ideal gases, the notion of temperature can be described in two different ways, the kinetic temperature and the thermodynamic temperature. For the Boltzmann distribution, the two notions lead to the same result. However, for a general probability density function, while the kinetic temperature has been commonly used, there appears to be no corresponding general definition of thermodynamic temperature. In this paper, we propose such a definition and show that it is connected to the Fisher information associated with the distribution of the momenta.

 

Thursday, 1:00 p.m.  P. Gibilisco.  Title: An invitation to the geometry of classical and quantum Fisher information.  Abstract: In 1945 Rao was the first to observe that Fisher information can be seen as a Riemannian metric on statistical models (in his classical paper establishing the so-called Cramer-Rao inequality). This observation remained as a side remark until Chentsov in 1972 proved that Fisher information is the unique Riemannian metric (on the simplex of probability vectors) that contracts under coarse-graining.  The Chentsov uniqueness theorem is the basis for a full understanding of the quantum theory for Fisher information. Indeed in 1996 Petz was able to prove a quantum analogue of the Chentsov theorem: in the quantum theory there is a family of Fisher information(s) and they are classified with the help of the theory of operator monotone functions (Lowner) and the theory of operator means by Kubo-Ando.  The first purpose of this talk is to introduce the existing bijections linking means, monotone functions and Fisher information. After this introduction a recent result, relating quantum Fisher information and the uncertainty principle, will be described.  Reference:  P.Gibilisco, D. Imparato, T.Isola.  A Robertson-type uncertainty principle and quantum Fisher information, Lin. Alg. Appl.,  428: 1706--1724, 2008.

 

Friday 9:00 a.m.  C. Vignat.  Title: Why use Fisher information?.  Abstract:  In this talk, I will try to justify the relevance of the use of Fisher information in some problems of information theory.  Inequalities between Fisher information and other measures of information such as entropy or moments will be discussed. An application to the detection of non-stationarities in random signals will be presented.

Students in the News

 

Rolyn Optics Outstanding Graduate Teaching Assistant Awards

 

Once again, John Ross of Rolyn Optics Company is rewarding three Optical Sciences teaching assistants for the outstanding work they did last semester.

 

Justin Bergfield was nominated by Masud Mansuripur for his work as teaching assistant in Opti 501, Electromagnetic Waves.

 

Goldie Gibbons was nominated by Mike Nofziger for her work as assistant in his Opti 201L, Geometrical and Instrumental Optics Lab.

 

Ryeojin Park was nominated by John Greivenkamp for her work in Opti 502, Optical Design and Instrumentation. 

 

The awards recognize outstanding performance as a teaching assistant or associate.  Because the nature of the award involves a high degree of excellence seldom seen even among our very talented students, the awards have gradually acquired great prestige among the faculty members who nominate their students and are prized by the students chosen to receive them.

 

John Ross, President of Rolyn Optics Company, created this series of awards especially for Optical Sciences students in 1997 and, as of today, he is an unofficial grandfather to 60 of our best graduate teaching assistants.

 

A no-strings-attached cash prize is part of the award and students have used the prize in many different ways including tuition and fees associated with attending grad school, financing summer internships, travel, expenses associated with beginning a family, and beefing up a savings account for the future.

 

Congratulations Justin, Goldie, and Ryeojin.

Yuan Luo Receives GPSC's 2008 Outstanding Research Assistant Award

 

The Graduate and Professional Student Council recognizes graduate students, staff and faculty who have made outstanding contributions to the campus and to graduate education.   Yuan Luo, College of Optical Sciences Graduate Student, was nominated and awarded the Graduate and Professional Student 2008 Outstanding Research Assistant Award.

 

During Graduate Student Appreciation Week, Yuan will be acknowledged for this award and his outstanding contributions at a special GPSC awards luncheon. 

 

A few weeks ago, Yuan was selected to receive OSC's 2008 Outstanding Graduate Student Award. 

 

Congratulations, Yuan.

 


 

Elaine Ulrich is Selected as the 2008 APS Congressional Fellow

 

After she receives her PhD in August, Elaine will travel to Washington where she will work for a Senator or Congressional Representative as a science policy advisor for one year.  The Fellows program is extremely popular with Members of Congress, few of whom possess a scientific or technical background.  Competition for the limited number of Fellows is intense as science is a major component of many issues with which Congress must grapple: global warming, energy policy, defense technologies, AIDS, pollution, communications technologies, and many, many more.

 

In turn, the program enables scientists to broaden their experience through direct involvement with the legislative and political processes. Fellows gain a perspective which, ideally, will enhance not only their own careers but also the physics community's ability to more effectively communicate with its representatives in Congress. Today's budget climate makes this ability of increasing importance as shrinking resources force hard choices between worthy projects.

 

Qualifications for Fellowships include a PhD in physics or a closely related field, APS membership, and U.S. citizenship. 

 

OSC alumnus, Elke Ertur Koehler, MS 1993 and PhD 2000, who gave a talk at our Community Speakers series at the beginning of March, was an AAAS Congressional Fellow.  She served as a science advisor to Senator Joseph I. Lieberman (D-CT) performing background research for legislation, drafting bills and amendments, preparing questions for witnesses at Senate hearings, and writing Senate floor statements, speeches and position papers on science and technology related issues.

 

Congratulations Elaine.  Please keep in touch to let us know what you're doing.

 


 

Question of the Week

 

Are Elaine and Elke our only Congressional Fellows, or have there been others over the years?

Steve Jacobs' Sun Clock #2 is Installed at Kitt Peak

 

Sun clock #1, installed a few years ago near the entrance to the Visitors Center at Kitt Peak National Observatory, had to be replaced recently.  The first sun clock was beautiful, but this second version is absolutely stunning.  Please click on the thumbnail at right for a larger image.

 

Perhaps you remember the story behind Steve's sun clock #1. 

 

Steve says he was inspired by the sunshine hours (Campbell-Stokes) recorder at the Royal Stockholm Observatory, and decided to design a similar configuration to tell time at Kitt Peak National Observatory.  In the Stockholm Observatory version, when the sun moves over Stockholm, a beautiful polished glass sphere burns a record of the sunny hours on a paper that’s replaced every day.  Steve's' version is paperless:  the central focal spot forms an image on a ground glass that is marked off in hours.

Senior Optical Design Engineer.  Lightfleet.  Lightfleet is an emerging early staged Pre-IPO growth company that has invented the world's first free-space broadcast optical interconnect.  Simply put, Lightfleet has created a new way for computers to communicate using light instead of wires.  Lightfleet's CorowaveTM technology streamlines computer-to-computer communication by empowering computers to directly talk to each other over short distances through the air with broadcast light.  Why is this important?   The biggest technology revolution in the way we work, learn, play, and interact with the world has just begun. The growing tidal wave of demand for digital data is unprecedented and will continue to grow geometrically in size for many years to come.  These highly dense computer installations produce a lot of heat that also must be removed and this can quickly more than double the total electrical power consumed. There is a growing concern over the cost of electricity and it is predicted that this cost will soon exceed the purchase price of the computer hardware it supplies.  Lightfleet's breakthrough technology allows our first product, an innovative form factor server, to be 1/3 the size and use 1/3 the electricity of any comparable product . . . while also being significantly faster by unleashing the true potential of parallel computing.    Senior Optical Design Engineer
