There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Optical crystalline micro-resonators: applications and challenges

Where: Van Leer W218
When: Tuesday Aug. 16th, at 2:00 pm
Abstract: Optical resonators with whispering gallery modes have found numerous applications in scientific research due to small mode volume and record high optical Q factors. WGM resonators made with ultrapure crystals hold the Q factor record of above 100 billion at room temperature. Crystalline resonators have several key applications such as frequency comb generation, nonlinear and quantum optics, optical communications and precise measurements. Some challenges and possible future directions of crystalline resonator technology will also be outlined in this talk.
Speaker Bio: Ivan Grudinin (Physics Ph.D., Caltech 2008) is a research technologist with the JPL’s Quantum Sciences and Technology group. Dr. Grudinin developed a class of compact record-high Q optical resonators. He used these devices as precise measurement tools to study a broad range of phenomena including the first demonstration of a phonon laser, one of the first demonstrations of microresonator Kerr frequency combs, efficient Raman/Brillouin lasers, and measurement of fundamental thermal noises. His research interests include optical microfabrication, frequency standards, cavity optomechanics, quantum and nonlinear optics. You can find you more about the speaker at http://grudinin.com/.
