Although liquid crystal polarization grating (LCPG) has a lot of attractive applications such as augmented reality and polarization imaging, most of the LCPG are optimized for visible wavelength. LCPG optimized for infrared (IR) wavelength should open new applications such as IR polarization spectroscopy and IR polarization imaging. In this presentation, we tried to fabricate LCPG optimized for infrared (IR) wavelength.
