Today's Colloquium: 3:30 p.m. Meinel 307
OSC alumnus Yong-Hee Lee, PhD 1986, now with the Korea Advanced Institute of Science and Technology Department of Physics, will present Two-Dimensional Photonic Crystal Nanolasers. Hyatt Gibbs is the host.
Abstract: Recent progresses towards the smallest possible semiconductor photonic crystal lasers are to be discussed. Especially electrically-driven single-cell nondegenerate lasing cavities with a central node will be explained in detail. In addition, the effect of symmetry perturbation on photon coupling from a wavelength-scale photonic crystal resonator is discussed. And our recent demonstration of the reconfigurable microfiber-coupled photonic crystal resonator that confines photons in a Gaussian-potential-well will also be presented.

Bio: Professor Lee received his PhD in Optical Sciences at the University of Arizona. During his stay at AT&T Bell Laboratories, he demonstrated the 850-nm proton-implanted top-emitting VCSELs in 1990. In 1991, he joined the Department of Physics in KAIST and has continued his researches on VCSELs. Recently his main interest lies on photonic band gap laser structures and nano-photonic integrated optical circuits. His laboratory demonstrated various forms of 2-D photonic band gap lasers from triangular and rectangular lattices. He received the National Academy of Sciences Award (Natural Science) in 2002 and the 2003 IEEE LEOS Distinguished Lecturer Award. He was elected as an IEEE Fellow in 2007. He co-authored more than 140 international journal papers related to VCSELs and photonic crystals. He is serving as an associate editor of Optics Express.
Friday's OSC Community Speakers: Noon. Meinel 410 Sponsored by the OSA/SPIE Student Optics Chapter
(1) At noon, Michael Kudenov will present Reverse Engineering of a Consumer Digital SLR for Affordable Astronomical Imaging: Thermal and Amplifier Noise Reduction.
Abstract: The use of CCD and CMOS imagers in amateur astronomy has increased significantly over the past decade. The primary reason for this digital boon is, of course, the decreasing cost and increasing performance of digital imagers. However, astronomical imaging is significantly more demanding than conventional imaging. So while costs have decreased in the consumer market, costs are still somewhat high for mid-range (~ 0.39-1 Mpixels) dedicated astrophotographic imagers most amateur astronomers have access to. Higher-range systems (> 4 Mpixels) are usually way beyond financial reach. This is the primary reason why digital SLR cameras have been popular as of late for amateurs: high resolution at a low price with good performance, however theres still much to be desired. In this talk, I discuss the conversion of an inexpensive Canon Digital Rebel 6.1 Mpixel SLR into a dedicated astrophotographic system, optimized for low noise long-exposure (> 1 hour) astronomical imaging. Examples of the noise before and after the modification, details on the circuit, as well as some images that I have taken with the camera through my telescope will be presented.
(2) At 12:30, Pierre-Alexandre Blanche will present The Holographic 3D Display Project.
Abstract: The aim of this project is to generate refreshable holographic 3D images using a photorefractive polymer material. Photorefractive polymers are organic materials that change their index of refraction when illuminated. So they can be used as a holographic recording medium. Prof. Peyghambarian's group study those materials since more than 10 years and has been the on the forefront in major discoveries on that topic. Photorefractive materials are now mature for applications and we are developing a large display playing 3D images that can be erased and refreshed within a few minutes. Other target applications are: laser beam amplification, signal restoration, non-destructive testing, data storage
Next Week's Colloquium: 3:30 p.m. in Meinel 307
OSC alumnus Till W. Liepmann, PhD 1983, will present Technology and Science of the JWST Space Observatory.
Abstract: This presentation will describe the desire of cosmologists and the technology behind the development of the future cryogenic space based telescope. Topics will include the optical design of the telescope, details of the instruments, interesting information about the "orbit", and discussion of what we hope to learn from this project. There are several technologies that had to be developed for this project, including image based adaptive optics, cryogenic opto-mechanical structure, large detector focal plane arrays, MEMS micro shutters, light weight beryllium mirrors, hexapod actuators, and cryogenic electronics.
Unusual Antique Optics on Loan to OSC
If you have a few minutes to spare, take a short elevator ride to the seventh floor where the bridge between the original building and the new West Wing currently houses a very special collection of twin-telescope binoculars on loan from David Steed. The unusual binoculars complement OSC's permanent collection of antique and historic telescopes, microscopes, lenses, and cameras. The permanent collection is housed at various locations throughout OSC and visitors are welcome Monday through Friday, 8:00 a.m. to 5:00 p.m.
Just Published
Geometrical and Trigonometric Optics by Eustace L. Dereniak and Teresa D. Dereniak.
Hardcover: 424 pages. Publisher: Cambridge University Press. Language: English. ISBN-10: 0521887461. ISBN-13. 978-0521887465.
The book is due to be released on September 30. Copies will be available through UA's bookstore or you may pre-order a copy through Amazon.com.
Here's what the publisher, Cambridge University Press, has to say about the book:
"A comprehensive treatment of the subject, the textbook begins with how light is generated, and how fast it travels. The concepts of how materials, such as glass, interact with light, and how various materials affect the velocity of light, are discussed, as well as the famifications of change in the speed of light. The concept of the index of refraction, and how it is used with Snell's law to produce image forming systems, is developed.
"An ideal textbook for advanced undergraduate level courses in geometrical optics, this book will also interest those who wish to learn the concepts and theory of geometrical optics. Each chapter contains worked examples, and there are exercises to reinforce the reader's understanding of the material."
The book grew out of class notes developed for Eustace's undergraduate optics classes here at OSC and is designed to be completed during a 16-week semester. Eustace's list of people who helped and encouraged the writing of the book reads like a Who's Who of Tucson's optics community: Bill Wolfe, Bob Shannon, Margy Green, Barbara Grant, Tracy Heran, Trish Pettijohn, Andre Alenin, Andrea Amaro, Erik Arendt, Riley Aumiller, Ruth Burzik, Ken Cardell, Erika Counselor, Julia Craven, Steven Dzuiban, Les Foo, Nathan Hagen, Darren Jackson, Michael Kudenov, Jeremiah Lange, KrIs LaPorte, Elias Martinez, Tracie Mosciski, Darren Miller, Jonathon Nation, Mike Nofziger, Viginia Pasek, Luz Palomarez, Logan Pastor, Jeff Richie, Louie Rosiek, Jim Scholl, Tim Shih, Katia Shtyrkova, James Tawney, Tomasz Tkacayk, Dorothy Tinkler, Corrie Vandervlugt, and Emma Walker.
Cambridge also gives us a short bio of the authors: "Eustace L. Dereniak is a Professor of Optical Sciences and Electrical and Computer Engineering at the University of Arizona. His research interests are in the areas of detectors for optical radiation, imaging spectrometers, and imaging polarimeter instrument development. Teresa D. Dereniak received her Bachelor of Science in Mechanical Engineering and a Masters in Business Administration from Cornell University. Her technical experience consists of product development engineering in the biomedical field."
Are the authors related? Yes. They are father and daughter.
