title: Infrared liquid crystal polymer micropolarizer.
abstract: The ability to create arbitrary patterned linear and circular infrared (IR) liquid crystal polymer (LCP) polarizers is demonstrated. The operating wavelength of the thin-film polarizer ranges from 700 to 4200 nm. The linear micropolarizer is fabricated using IR dichroic dye as a guest in LCP host with feature size as small as 4 μm. The circular micropolarizer is fabricated using cholesteric LCPs with feature size as small as 6.2 μm.
