Abstract:
1. A transmissive type optical image modulator comprising: a base substrate; a first epitaxial layer formed on the base substrate; a plurality of second epitaxial stacks formed on the first epitaxial layer, wherein each of the plurality of second epitaxial stacks is separated from a neighboring one of the plurality of second epitaxial stacks by a trench disposed therebetween; a plurality of first electrodes formed on the first epitaxial layer and spaced apart from the plurality of second epitaxial stacks; a plurality of second electrodes, each formed on a respective one of the plurality of second epitaxial stacks; and a transparent substrate covering the plurality of second epitaxial stacks and the plurality of second electrodes, wherein the base substrate comprises a through hole corresponding to a light emitting area, and the first epitaxial layer is a continuous layer which corresponds to the plurality of second epitaxial stacks formed thereon, and wherein the first epitaxial layer comprises a top surface exposed by the plurality of second epitaxial stacks.
