Systems, methods, and device architectures for optical applications

Abstract

An OSC material may include a grating structure for use in waveguide applications. A method of patterning the OSC material to create the grating structure may include forming a hard mask over the OSC layer and etching the OSC layer through an opening in the hard mask. Furthermore, an improved design of a grating light valve device may include a reflective backplane, an array of micro-ribbons disposed on the reflective backplane, and a metasurface structure positioned beneath the array of micro-ribbons. A multiple stage process may include generating a broad spectrum of light from a laser architecture, filtering and multiplexing the wavelengths of light using an image optimization module, and incoherently averaging the speckle patterns across the various wavelengths using a spatial light modulator architecture.
