Diffraction gratings made from optically anisotropic material with surface microrelief

The diffraction of polarized light transmitted through an optically anisotropic substrate with surface microrelief is calculated using the Exedeep program (optically anisotropic lattices with surface microrelief). The diffraction parameters are determined in different diffraction orders of transmitted and reflected TE and TM waves for materials with both positive and negative optical anisotropy. Such materials can be low- and high-molecular-weight calamitic and discotic liquid crystals. The results of modeling are used to create diffraction optical elements that operate in the visible, IR, and terahertz ranges. (C) 2021 Optical Society of America
