Abstract

A well known antireflection (AR) coating for an air (n_a)–glass (n_g) interface and normally incident light is constructed by depositing a quarter-wave of a high index material (n_H) followed by a quarter-wave of a low index material (n_L).¹ In this presentation we expand the scope of the AR coating so that it is antireflecting for one linear polarization which we designate p, but gives a reflectance of a few percent for the mutually perpendicular s polarization. Potential applications of the anisotropic antireflection (AAR) coating² include polarization-selection devices for lasers, replacing the Brewster-angle plate which requires considerable space in an optical cavity.
