Devices and systems for light-recycling waveguides

Abstract

The disclosed device may include a waveguide; an output coupler that couples electromagnetic radiation from within the waveguide to outside of the waveguide; and a reflector positioned on an opposite side of the waveguide from the output coupler, where the reflector reflects electromagnetic radiation that leaks from the waveguide through the opposite side of the waveguide back toward the output coupler. Various other devices, systems, and methods are also disclosed.
