Summary We fabricated and characterized a thin photo-patterned micropolarizer array for complementary metal-oxide-semiconductor (CMOS) image sensors. The proposed micropolarizer fabrication technology completely removes the need for complex selective etching. Instead, it uses the well-controlled process of ultraviolet photolithography to define micropolarizer orientation patterns on a spin-coated azo-dye-1 film. The patterned polymer film micropolarizer (10 mu m x 10 mu m) exhibits submicron thickness (0.3 mu m) and has an extinction ratio of similar to 100. Reported experimental results validate the concept of a thin, high spatial resolution, low-cost photo-patterned micropolarizer array for CMOS image sensors.
