Abstract

A light modulator for amplifying an intensity of incident light and modulating a phase of the incident light is provided. The light modulator includes: a first distributed Bragg reflector (DBR) layer having a first reflectivity and comprising at least two first refractive index layers that have different refractive indices from each other and are repeatedly alternately stacked; a second DBR layer having a second reflectivity and comprising at least two second refractive index layers that have different refractive indices from each other and are repeatedly alternately stacked; and an active layer disposed between the first DBR layer and the second DBR layer, and comprising a quantum well structure.
