Photorefractive Mode Conversion for Fault-Tolerant Source-Fiber Coupling.
Abstract
The purpose of this contract to study the potential applications of nonlinear optical phenomena in photorefractive materials in various geometries (such as waveguides, fibers, and bulks) for efficient and fault-tolerant laser-to-fiber coupling. The study focuses on the development of new application concepts, theoretical modeling and experimental demonstration/characterization of novel devices based on energy coupling among different optical modes via dynamic holograms in c-axis photorefractive waveguides and fibers; and on optical resonators incorporating photorefractive dynamic holograms in bulk crystals. The holograms are self-generated by the interaction of various optical modes (waves) propagating through the photorefractive material. The final objective is to identify an optimum material and configuration and to demonstrate a higher coupling efficiency and better fault-tolerance in coupling light from a laser to an optical fiber or waveguide than that achievable by the conventional method.
