Abstract

See full text

An infrared wire grid polarizer is fabricated on an infrared transmissive substrate and consists of alternating transmissive and conductive zones disposed thereon. These polarizers are particularly well suited for use with acoustic-optic tunable filters and can be employed as input and output polarizers therewith. A method of manufacturing a wire grid polarizer with at least 4000 conductors per millimeter is disclosed. The infrared transmissive substrate is selected from the group consisting of silicon crystal and gallium arsenide crystal.
