Abstract

An optical amplitude modulator, comprising: a first transparent conductive terminal; a second transparent conductive terminal; a transparent insulator layer; and a transparent semiconductor layer; wherein the insulator layer and the semiconductor layer are sandwiched between the first terminal and the second terminal; and wherein a transmissivity of electromagnetic radiation through the insulator layer and the semiconductor layer is dynamically controllable according to a voltage applied between the first terminal and the second terminal.
