Random laser, bio-inspired laser, and time-reversed laser – Hui Cao
Date: Thu. March 28th, 2013, 4:15 pm-5:15 pmLocation: Rockefeller 301
In this talk, I will review our studies of photonic nanostructures of random morphology. First, I show how we can trap light in such structures to make random lasers. Next, learning from the non-iridescent color generation by isotropic nanostructures in bird feathers, we use short-range order to enhance light confinement and improve lasing efficiency in artificial nanostructures. Finally I will introduce our recent work on time-reversed laser – coherent perfect absorber.
