Complex photonic nanostructures and phenomena
à 11h en salle C. Brot
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 shortrange order to enhance light scattering and confinement in artificial nanostructures. Finally I will introduce our recent work on time-reversed laser - coherent perfect absorber.
