Abstract
A nonlinear optical device includes a layered semiconductor structure having layers of different energy band gap materials. Alternate layers of the structure are arranged for containing trapped charge. An input light beam is applied to the layers. A control light beam varies the trapped charge for controlling propagation of the input light beam through the structure.
