DOI: 10.1364/ao.453891
Abstract: Spectral filters with polarimetric character in short-wave infrareds are urgently needed because of their broad applications in optic-fiber communications, polarimetric detections, and imaging. Based on our earlier progress in developing polarimetric devices in infrared wavelengths,… read more here.
