A Broadband Apparatus for Generating and Sampling Polarization States
Researchers at the University of Arizona have developed thin-film polarization devices that generate and/or sample light-polarization states over a broad band (wide wavelength range) and over wide angles. The polarizers incorporate and exploit multiple polarization layer groups and can be integrated into a microarray and incorporated into a light source...
