APPARATUS FOR PLASMONIC NANOANTENNA OPTICAL BEAM PHASE-SHIFTER AND STEERER

摘要

A pixel for creating an optical phase change includes a transparent electrical insulator, a first electrical conductor disposed on the transparent electrical insulator, the first electrical conductor comprising an antenna component and a connector component, an electrical insulator disposed on the first electrical conductor, a transparent semiconductor disposed on the electrical insulator, and a second electrical conductor disposed on the transparent semiconductor. The transparent semiconductor is sufficiently thick to prevent plasmonic resonance from occurring at an interface between the transparent semiconductor and the second electrical conductor.
