CREOL Colloquium Series: Girish Agarwal "Quantum Imaging and Sensing beyond Rayleigh Resolution"
Friday, February 29, 2008 10:30 AM to 12:00 PM CREOL Room 102
G S AgarwalDepartment of Physics, Oklahoma State University, Stillwater, OK 74078
One question of great importance in the field of imaging is the issue of the resolution which has been considered to be limited by the Rayleigh criterion. However recently one has developed several methods by which this limit can be overcome. Some of these newer possibilities include use of evanescent waves [plasmonics ] and the use of sources of light which produce entangled photon pairs. I would describe the progress made using entangled photon pairs. I would show how stimulated parametric processes along with spontaneous ones are especially useful in producing high visibility and large signals at high gains of the parametric process. I address both the questions of super resolution and super sensitivity. The entangled photon pairs have also very promising applications in the context of sensing with quantum light and in particular to light scattering. Professor Girish Agarwal has been a world leader in quantum optics for more than twenty five years. His scientific contributions provided new directions of research in quantum optics: cooperative resonance fluorescence; the development and application of master equation techniques which enable one to understand key problems like quantum Brownian motion, superradiance and optical bistability. He laid the foundations for optical resonance and nonlinear optical phenomena in partially coherent fields; quantum electrodynamic phenomena at surfaces; vacuum Rabi splittings in high Q-cavities; and the control of the efficiency of nonlinear optical processes.
Prof. Agarwal’s work has been recognised by a very large number of national and international awards, including the Max-Born Prize from the Optical Society of America in 1988, the Physics Prize of the Third World Academy of Sciences in 1994.He is a Fellow of the American Physical Society, the Optical Society of America He was honored with the prestigious Humboldt Research Award (1997) of Germany. Very recently he received Honorary doctorate from the University of Liege, Belgium.
During his career, Prof. Agarwal has published more than 500 papers in top international journals, including extensive review articles and a research monograph. Prof. Agarwal serves on the editorial boards of many international journals and is also a topical editor for the Journal of the Optical Society of America A. His current research work is primarily in quantum optics with applications in quantum information science.
