Vector polarizers are a light filtering technology hidden behind the operation of many optical systems. They can be found, for instance, in sunglasses, LCD screens, microscopes, microprocessors, laser machining and more. Optical physicists from Nanjing and Nankai University, China, and the University of Central Florida, U.S., published details of their new vector polarizer design this week in APL Photonics. The newly proposed design is a major advance in polarization technology because it enables flexible filtering of a wide range of light sources and generation of new light states.
