Today's Colloquium September 24. 3:30 p.m. Meinel 307
Charles Falco, University of Arizona College of Optical Sciences, will present Computerized Image Analysis: Examples and Insights From 1000 Years of Optical Projections. Mahmoud Fallahi is the host.
Abstract: The hands and mind of an artist are intimately involved in the creative process of image formation, intrinsically making paintings complex to analyze. In spite of this difficulty, several years ago the artist David Hockney and I identified optical evidence within a number of paintings that demonstrated artists began using optical projections as early as c1425 — over 150 years before Galileo — as aids for producing portions of their images. Looking for even earlier evidence led us to the 11th century scholar Ibn al-Haytham (Latinized as Alhazen or Alhacen), who wrote nearly one hundred works on topics as diverse as poetry and politics. Today al-Haytham is primarily known for "Alhazen's problem," his treatment of a particular geometry of reflection from flat and curved surfaces. However, as I will discuss, with his landmark seven-volume Kitāb al-Manāzir [Book of Optics], published 1028~1038, al-Haytham made intellectual contributions that subsequently were incorporated throughout the core of post-Medieval Western culture. In the course of this work, Hockney and I developed insights that I have been applying to a new approach to computerized image analysis. One direct result was to identify from Impressionist paintings by Monet, Pissarro, Renoir and others the precise locations the artists stood when making a number of their paintings. Indirect results have been the development of a high resolution infrared camera, and a project to produce filters for a multispectral camera presently scheduled to begin capturing images from Jupiter's moon Europa in 2026. Acknowledgments: I am grateful to David Hockney for the many invaluable insights into imaging gained from him in our collaboration, and to the support of ARO and DARPA.

Friday's Deadline: Sign Up for our Fourth Annual LBT Camping Trip
Our Fourth Annual Large Binocular Telescope trip date is Saturday, October 3. Come up just for the day or stay the night and camp with your fellow OSC students, staff and faculty. We will ride in OSC-provided vans, but you can also drive yourself. Last year about 90 people attended. Guests are welcome. Breakfast will provided to overnight campers on Sunday morning, cooked by your SOCk officers.
Please RSVP by 5:00 p.m. on Friday, September 25. This is absolutely critical. We need to register you in advance as the LBT is a controlled-access facility located inside the red squirrel refuge. RSVP to to Katia Shtyrkova at katiasht@email.arizona.edu. And drop by Anabel Garcia's office in Meinel 403 to give her your deposit: $5 per person. Your RSVP isn't complete until you pay the deposit.
Questions? Please contact Robin Palit at rpalit@optics.arizona.edu or Stefano Young at syoung@optics.arizona.edu
Next Week's Colloquium October 1. 3:30 p.m. Meinel 307
Marko Loncar, Harvard University School of Engineering and Applied Sciences, will present Optical Nanostructures for Advanced Communication Systems. Masud Mansuripur is the host.
Abstract: Wavelength-scale optical resonators can enable on-chip manipulation of photons, and will be important building blocks for optical- and quantum-communication systems. We recently demonstrated photonic crystal nanobeam cavity1,2 , fabricated in silicon, that supports modes with quality factor Q~106. Furthermore, by taking advantage of mechanical degrees of freedom of two coupled-nanobeam cavities3, we demonstrated reconfigurable optical filters4 that could be dynamically and reversibly tuned. In our structure, that combines NEMS with nanophotonics, an external bias voltage controls the separation (<100nm) between the nanobeams via the electrostatic force, which in turn has a strong effect on the resonant wavelength of the structure. We demonstrate tunable filters with a tuning range of ~10nm, using less than 6V of external bias and negligible steady-state power consumption4. Bright single-photon source based on diamond nanowire5, that we recently discovered, is another example of novel functionalities enabled by nanostructuring. Nitrogen vacancy (NV) color center in diamond has emerged as promising quantum emitter that combines the key advantages of isolated atomic systems with solid-state integration. In order to further improve the efficiency of NV-based quantum-emitters, it is important to enhance the collection efficiency of emitted photons. We achieved this using nanowire-antenna approach, and demonstrated an order of magnitude larger collection efficiency over devices based on bulk diamond crystals.

Scholarship Announcements
Our Academic Programs office has just announced the following Scholarship recipients:
Jonathan Nation has been selected to receive this year's James M. Palmer Endowed Scholarship. The scholarship honors Jim Palmer, teacher and mentor to a generation of Optical Sciences students. Dr. Palmer was a key figure in the formation of OSC's Bachelor's degree program in the late 1980s, helping to develop the curriculum and teaching several of the required courses. In addition to his substantial and sustained contributions to optics education, Jim's research in sensor-system calibration significantly advanced the state of the art in that field.
After his death in 2007 from chondrosarcoma, Jim's family, friends, associates, and former students contributed generously to endow a scholarship in his honor. The scholarship is available to third-to-fifth-year undergraduate students enrolled in the College of Optical Sciences program who are making satisfactory progress and are engaged in other activities outside of their academic pursuits. Preference may be given to students who demonstrate a need for financial assistance.
SCHOTT is a multinational, technology based group developing and manufacturing special glass, specialty materials, components and systems for more than 125 years to improve how people live and work. The beautiful glass sculpture on display in our lobby was crafted by artist Christopher Ries and is a gift from SCOTT. For more information about SCHOTT, please visit www.us.schott.com
Noel Eloriaga, Carlin Kartchner, Brittany Lynn, Taylor Sorensen, and Javier Yanez have been selected to receive the John Tipton Scholarship in Optical Sciences. The scholarship, established by generous contributions from Dr. Sean McCafferty, supports or is a recruitment incentive for outstanding undergraduate students who are U.S. citizens maintaining a minimum 3.0 GPA and a demonstrated need for financial assistance. Incoming freshman are eligible to compete for the award having received a minimum 3.4 GPA from their respective high schools. All candidates must qualify as need-based students in accordance with the Free Application for Federal Student Aid program standards (FAFSA).
Congratulations students.
DARPA Young Faculty Awards
It's a real honor for Optical Sciences to have two faculty members receiving DARPA's prestigious Young Faculty Award. Both Jason Jones and Stanley Pau received the $300,000 award for two years, beginning this fall.
Jason received his PhD from the University of New Mexico in 2001. Before joining our faculty in 2004 he was with JILA at the University of Colorado.
Stanley received his PhD from Stanford University in 1996. Before joining our faculty in 2005 he was with Lucent Technologies Bell Labs in the Nanotechnology Fabrication Laboratory and a PostDoc at Max Planck Institute of Solid State Physics in the Spectroscopy Group.
About the DARPA Young Faculty Award Program
The DARPA Young Faculty Award (YFA) program identifies and engages rising research stars in junior faculty positions in academia and exposes them to Department of Defense (DoD) needs and DARPA's program development process. The YFA program provides high-impact funding to these rising stars early in their careers in order to develop their research ideas in the context of DoD needs. The long term goal is to develop the next generation of academic scientists, engineers, and mathematicians in key disciplines who will focus a significant portion of their career on DoD and National Security issues.
