FIELD INVERSION WAVEGUIDE USING MICRO-PRISM ARRAY

摘要

A field inverting optical waveguide is disclosed. The waveguide is configured to convey electromagnetic radiation from an ingress end to an egress end along an optical path. The waveguide includes an optically flat input surface disposed at the waveguide ingress end, and an exit surface disposed substantially opposite the input surface at the waveguide egress end. The exit surface includes an array of prisms projecting outward from or inward to the exit surface. The input surface and the exit surface are arranged substantially orthogonally to the optical path.
