Abstract

A spatial light modulator includes a variable refractive index layer that has a refractive index which is variable based on one of an optical signal and an electrical signal, a metal layer that is disposed on the refractive index-change layer, and a high refractive index layer on the metal layer. Light incident on the metal layer causes generation of a surface plasmon at an interface between the variable refractive index layer and the metal layer.
