Abstract
This disclosure provides an apparatus for modulating light, the apparatus comprising a substrate having a plurality of electrical interconnects disposed on its top surface and an array of optical modulation elements disposed on the substrate. The optical modulation elements of the apparatus include an array of optical modulation elements, the array including a bottom electrode disposed on the substrate, wherein the bottom electrode is coupled to an electrical interconnect among the plurality of electrical interconnects, a bottom surface of a first dielectric layer is located above the bottom electrode, and a quantum well layer covering the top surface of the first dielectric layer. A second dielectric layer is then configured to cover the top surface of the quantum well layer, wherein each optical modulation element of the optical modulation element array is spatially separated from each of the other optical modulation elements of the array, and the top electrode is located on top of the optical modulation element array.
