Abstract

A polarizer is provided comprising a subwavelength optical microstructure wherein the microstructure is partially covered with a light-transmissive inhibiting surface for polarizing light. The inhibiting surface can include a reflective surface, such as a metalized coating. The subwavelength optical microstructure can include moth-eye structures, linear prisms, or modified structures thereof. A polarizing structure is further provided comprising a plurality of moth-eye structures stacked on one another for polarizing light.

Claims (2)

1. An optical polarizer film comprising a substrate having a subwavelength moth-eye structure including peaks and valleys, an intermittent surface covering at least a portion of the structure, and a conductive coating disposed on the intermittent surface in at least some of the valleys and providing polarization.

2. The optical polarizer film of claim 1 , further comprising a substantially transparent coating disposed on the polarizer film.
