Title:

Nano-Optoelectronics for Communications

Host:

Nasser Peyghambarian

Abstract:

In this talk, I will like to provide an overview of some of the projects we are working on.  Specifically, I will talk about two projects, III-V nanowire on Si and high-index contrast grating VCSEL.  Heterogeneous integration of optoelectronic active devices (diode lasers) with CMOS integrated circuits (IC) has been a subject of great interest for a couple of decades.  But solutions remained to be illusive.  The key bottleneck has been process incompatibility of the two types of material systems.  In this talk, we discuss the synthesis and characterization of III-V nanowires onto a Si substrate at low growth temperature in the range of 380~450 C using MOCVD.  The small dimension of nanowires (diameter <20 nm) enables low defect growth of active region despite a large lattice mismatch.  The low temperature growth and the large-scale manufacturability of an MOCVD system make this approach very promising.  Finally, I will discuss a VCSEL incorporating a novel high-index contrast subwavelength grating.  The HCG is less than 0.23 um thick, can provide very high reflectivity and wide bandwidth.  By integrating a movable, single-layer HCG as the VCSEL top mirror, single mode emission (SMSR >40 dB) and continuous wavelength tuning (~2.5 nm) was obtained at room temperature under CW operation. The small footprint of HCG enables the scaling down of each of the cantilever dimensions by a factor of 10, leading to 1000 times reduction in mass and increase in the mechanical resonant frequency.  Hence, a NEMO tunable VCSEL with tuning speed in the GHz range can be potentially realized.

 

Friday's OSC Community Speakers -- April 20, 2007 -- Noon -- Meinel

 

From Scott Gibb.  Faculty, Staff and Students, This Friday April 20th is the last Community Speaker's event of the school year. It has been a fun year - I've enjoyed it and I hope everyone did as well. Barbara, Cynthia, Mary Lou and Bob deserve a big thank you for organizing and setting up the pizza lunch for every event. The pizza distribution was incredibly smooth this past year.

 

For this Friday, Matthew Kupinski will present Image Quality Assessment in Medical Imaging.  Description: The quality of an imaging system is not determined by properties such as resolution or noise level, but by the useful information that can be extracted from the images the system produces. In this talk, I will introduce the idea of task-based assessment of image quality and discuss the applications of this methodology to medical imaging. 

 

Next, Hong Hua will present Smart Ways to Use Projectors and Cameras.  Description: Digital projectors and cameras are not just for presentation and picture shooting, their combination can lead to very creative research ideas. In this talk, instead of focusing on my own research which was presented a few times, I am going to review a few different ways that other researchers have been using camera-projectors to create new display environments and novel human computer interaction techniques.

 

PS - Fellow grad students, if any of you are interested in organizing Community Speakers next year let me know and I'll tell you what's involved.

Title:

Metamaterial-Enabled Resonant Electrically-Small Scattering and Radiating Systems in the Microwave and Optical Regimes

Host:

Scott Tyo

Abstract:

There continues to be a great desire for high performance electrically small radiating and scattering systems from the microwave to the optical regimes whose physical characteristics and electromagnetic responses could be tailored to satisfy a wide range of applications.  Metamaterials, artificial materials whose electromagnetic responses can in principle be engineered to any negative or positive value, have been shown recently to be a potential enabling technology for these radiating and scattering systems.   Traditional electrically small radiating and scattering systems are poor transducers of their input or excitation energy. Several metamaterial-based configurations have been demonstrated recently that significantly improve the radiating and scattering performance characteristics of these systems.  The resulting systems are resonant despite being significantly sub-wavelength in size.  For instance, an electrically-small epsilon-negative (ENG) or double negative (DNG) spherical shell surrounding an electrically-small dipole antenna can be designed to act as an effective distributed inductor that is properly matched to the capacitive electric dipole element to form a naturally resonant LC structure, as well as to act as a resistive matching element to the source. Thus, an overall efficiency of 100% can be achieved in such an electrically-small radiating system.   The reciprocal configuration, plane wave scattering from an electrically-small ENG or DNG metamaterial-coated sphere, has been shown to exhibit unity scattering. Moreover, by introducing gain media, the effects of losses and dispersion can be controlled. For instance, lasing has been demonstrated at visible wavelengths in an electrically-small metal coated nano-particle.  A review of the progress to date on all of these resonant metamaterial-based electrically small radiating and scattering systems, and their potential practical microwave and optical realizations will be given. The effects of losses and dispersion will be emphasized in the discussion.

 

Kurt Thome and Ewan Wright
Receive UA's College Awards of Distinction

 

Each Spring, the University of Arizona recognizes its faculty members for excellence in teaching.  This year, a  committee of faculty members and students has selected two College of Optical Sciences professors to receive the coveted Awards of Distinction:  Ewan Wright for outstanding graduate teaching and Kurt Thome for outstanding undergraduate teaching.  The award is new and has only been awarded a few times.  Previous recipients include Mike Nofziger, Eustace Dereniak, and Masud Mansuripur. 

 

Congratulations, Ewan and Kurt.

 

Scott Tyo Shares Award for Excellence

 

During a recent trip to Kauai, Hawaii to attend a National Consortium for MASINT Research technical review, Scott Tyo and two colleagues from the University of New Mexico, Sanjay Krishna and Majeed Hayat,  were awarded the Defense Intelligence Agency Chief Scientist's Award for Excellence. They received the award for their project, Quantum-Dot Sensors for MASINT Applications.

 

Scott provides the following details:  "The program ran from 2004 to 2007 and involved the development of spectrally agile focal plane arrays based on quantum dot technology grown at the Center for High Technology Materials at UNM. The spectral tuning is achieved without the use of filters, gratings, or other optical components. The patented technology is based on nanoscale quantum dots blended with signal and image processing strategies. The developed technology will would be useful for remote sensing of toxic chemical agents, chemical spectroscopy, and vegetation and geological/environmental monitoring. The project is administered by the National Science Foundation as Special Program, Award IIS-0434102.  This project has currently been transitioned to a related partnership project with Los Alamos National Laboratory for the development and system testing of a spectrally tunable mid-infrared focal-plane array. The NCMR R&D program seeks to promote MASINT-related research collaboration among academia, industry, laboratories, and government."

 

The National Consortium for Measures and Signatures Intelligence (MASINT) Research (NCMR) was the result of an FY03 Congressionally Directed Action. As directed by Congress, a five-year plan to advance research for Measurements and Signatures Intelligence was initiated and delivered to Congress in March 2003.

 

The five-year plan identified a set of technology areas where advancements would result in new MASINT systems. The Defense Intelligence Agency – Measurement and Signatures Intelligence and Technical Collection (DIA-DT) was directed to establish a basic MASINT R&D Program through the FY04 Intelligence Authorization Act, section 504.

Fall Prelims -- Date Change

 

It turns out that OSA's Annual Meeting is scheduled for the same week as our Fall Prelims this year, so we have changed our dates:  our Fall 2007 Comprehensive (AKA Prelims) Exam will be held on September 25 and 26.  Students, this is good news as it gives you an extra week to prepare.

 

 

Group Photo -- Save the Date

 

This year, our annual group photo is scheduled for the last day of classes:  Wednesday, May 2 at 1:00 p.m.  The location is still TBD, but we usually gather on the UA Mall or the grounds just outside of our building.  These annual photos are about the only way we have of remembering who was in our program in any given year, so everyone at OSC is invited and we hope to see you all there.  We are a large group and it takes a while for our photographer (Robert Walker, of course) to get us all organized, so please come a little early and allow about 20 minutes for the entire photo shoot.  BTW: Our collection of group photos from past years graces the hallway on the seventh floor, so if you haven't seen it yet, you are invited to check it out.

 

                                               Avoid the Mall -- Shop at OSC

 

If you're looking for a really cool t-shirt that you can't buy anywhere else, we have a deal for you:  our wonderful OSC t-shirts have just been marked down to $10 each.  The shirts are available in a variety of colors, sizes, and styles, so stop by Academic Programs in Meinel 403 and pick up a couple for summer.  Come to think of it, if you're looking for something nice to wear for the group photo, one of these shirts might be exactly what you need.
