Abstract
Fast, all optical switching of light is provided on silicon, using highly light confining structures to enhance the sensitivity of light to small changes in refractive index. In one embodiment, the light confining structures are silicon micrometer-size planar ring resonators which operate with low pump light pulse energies.
