Abstract

See full text

A semiconductor structure comprises a substrate, a patch of optically tunable material disposed over the substrate, a first electrode coupled to the patch of optically tunable material and a switch providing a current source, and a second electrode coupled to the patch of optically tunable material and a ground voltage. The first electrode and the second electrode are configured to modify a state of the patch of optically tunable material to adjust a reflectivity of the patch of optically tunable material.
