Differential switching operation of vertical cavity laser with depleted optical thyristor for optical logic gates

Abstract

Optical logic gates with AND, OR, and INVERT functionality are demonstrated by the monolithic integration of a vertical cavity laser with depleted optical thyristor. All kinds of logic functions (AND, OR, NAND, NOR, and INVERT) are experimentally demonstrated using a differential switching operation scheme by simply controlling an intensity of a reference input light.
