Seminar: “Complex Photonic Nanostructures and Phenomena” - Dr. Hui Cao CREOL 102 Tuesday, March 1, 2011 / 11am-12pm
Department of Applied Physics, Yale University
Wave optics is an old field of physics that has experienced rapid advances lately. Thanks to modern nanofabrication technology, complex nanostructures such as photonic crystals and metamaterials can be fabricated, and they display unusual optical properties and phenomena.
In this talk, I will focus on our studies of photonic nanostructures of random morphology. I show how we can trap light in such structures to make random lasers. Next, learning from the color generation by nanostructures in bird feathers, we use short-range order to enhance light scattering and confinement in artificial nanostructures. Finally I will introduce our recent work on time-reversed laser - coherent perfect absorber.
Hui Cao is a Professor of Applied Physics and of Physics at Yale University. She received a Ph.D. from Stanford University in 1997. Her main interests are in Nanophotonics and quantum optics. Her research focuses on understanding and controlling quantum optical processes in nanostructures, both for fundamental physical studies and for device applications. Professor Cao is a David and Lucille Packard Fellow and an Alfred P. Sloan Fellow. She won the Early CAREER Award from the National Science Foundation, and the Maria Goeppert-Mayer Award from the American Physical Society. She became a fellow of the American Physical Society and a fellow of the Optical Society of America in 2007. She has authored/co-authored one book, three book chapters, three review articles, and over one hundred and thirty journal articles. Cao chaired the OSA Technical Group on Photonic Metamaterials from 2006 to 2008. She served as the program co-chair for 2010 International Conference on Quantum Electronics and Laser Sciences (QELS).
