Mid-wavelength infrared (MWIR) polarizers are widely used for a variety of applications, including non-invasive medical diagnostics, gas detection, and night vision. Conventional MWIR polarizers are formulated with metallic semiconducting materials such as Ge, ZnSe, and ZnS due to their excellent IR optical properties. However, metallic materials are intrinsically rigid, expensive, and difficult to process. In this study, we introduce MWIR transparent sulfur copolymer arrays prepared by nanoimprinting lithography toward flexible and low cost MWIR polarizers. The variation of dimension (pitch, height, and feature size) of sulfur copolymer arrays provides tailoring capability for three dimensional low loss beam steering properties. In this presentation, we will discuss parameter studies for regulation of MWIR beam steering. |
