OPTICAL MODULATING DEVICE HAVING GATE STRUCTURE

摘要

An optical modulation device comprises: a plasmonic nano-antenna layer; a metal layer disposed to face the plasmonic nano-antenna layer; a dielectric varying layer disposed between the plasmonic nano-antenna layer and the metal layer; and a dielectric layer. The present invention can have a role as a gate that an active area formed on the dielectric varying layer according to an external signal controls the performance of optical modulation.
