Paper Abstract

A near-ideal, all-dielectric, reflection polarizer is described that employs selective totally destructive interference for the p polarization and constructive interference for the s polarization in a buried low-index (BLIND) film embedded in a high-index substrate near (within 10 degree(s) of) grazing incidence. A specific design is presented of an infrared polarizer that uses a film of refractive index 1.35 embedded in a Ge substrate of refractive index 4.1. Such a polarizer has a throughput for the s polarization of 92% and 99%, when operated at incidence angles of 80 degree(s) and 85 degree(s), respectively.
