WAVEGUIDE POLARIZATION BEAM SPLITTERS AND METHOD OF FABRICATING A WAVEGUIDE WIRE-GRID POLARIZATION BEAM SPLITTER

摘要

A method in effectuating the redirection of light which is propagated within a waveguide, and which eliminates the necessity for a bending of the waveguide, or the drawbacks encountered in directional changes in propagated light involving the need for sharp curves of essentially small-sized radii, which would resultingly lead to excessive losses in light. In this connection, the method relates to the fabricating and the provision of a wire-grid polarization beam splitter within an optical waveguide, which utilizes a diblock copolymer template to formulate the wire-grid.
