Abstract

We tried to develop the liquid crystal geometric phase elements (LCGPE) that are available for use in the midand far-infrared (MIR and FIR) wavelengths. In view of optical throughput, the materials for making GPE were selected by the use of a Fourier-transform infrared spectrometer. The LC polarization grating (LCPG) and LC q-plate (LCQP) designed for 3.85 µm and 9.5,µm are respectively fabricated, and evaluated their diffraction properties experimentally.
