Paper Abstract

In this paper, we demonstrate a wiregrid polarizer for the near-IR spectrum fabricated by nanoimprint techniques. High resolution grating structures with 215nm in linewidth, 375nm pitch and 235nm total height were patterned on silicon by deep-UV interference lithography followed by reactive ion etching. The grating structures were transferred to a SU-8 thin film by nanoimprint. Then a glancing angle deposition was performed to build the wiregrids. The extinction ratio was measured to be over 90:1 at 1064nm.
