The facile fabrication of a wire-grid polarizer by reversal rigiflex printing

摘要

Wire-grid polarizers (WGPs) can be fabricated easily by reversal rigiflex printing. Metal films with gratings were fabricated on a transparent glass substrate by transfer printing with a metal coated rigiflex mold, and the transferred metal gratings were then etched slightly to eliminate the residual layer. As a result, aligned metal wires (70 nm line/space width, 120 nm height) occupying an area of 3.0 cm × 2.5 cm were obtained. The maximum and minimum transmittances of a WGP replicated from a commercial Moxtek polarizer at 800 nm were 85% and 27%, respectively.
