Abstract

The materials and process technology necessary to fabricate free-standing, circularly-polarizing thin films based on chiral polymer liquid crystalline materials has recently been demonstrated. Free-standing membranes with thicknesses on the order of 10 microns and diameters in excess of 7 cm have been fabricated. The spectrally selective films possess exceptional optical and mechanical properties, exhibiting polarization contrast in excess of 250 with out-of-band transmissions greater than 95%. The theory, materials, processing techniques and spectral performance of these filters are presented.
