Abstract

The properties of wire-grid polarizers (WGP) are studied and optimized. Experimentally, the efficiency and the contrast ratio of the projection system using WGP are investigated as a function of the incident angle. It is confirmed that WGP can afford large extinction ratios and large numerical apertures (NA). However, WGP suffers from the drawback of large absorption by the metal grid. We calculated the properties of the WGP as a function of its physical parameters using rigorous diffraction theory. Optimal designs are obtained based on the criteria of best optical performances (high efficiency, large NA, large extinction ratio). With these optimal physical parameters the WGP can show very good performance with efficiency >85%, large NA, and high extinction ratio >1000.
