Abstract

An optical device includes a layered semiconductor structure having a variable input light beam applied to the structure with an E field component polarized normal to the layers. Intensity of the input light beam controls charge trapped in the layers, the dielectric constant of the layers containing the trapped charge, and the propagation of the input light beam within the device.
