Diffraction on Anisotropic Substrates with Sinusoidal Surface Microrelief

Light polarization management by diffractive optical elements (DOE) can enhance light efficiency in LCD backlight systems. The OAGSM software developed earlier provides calculation of diffraction efficiency for optically anisotropic gratings with periodical sinusoidal surface microrelief. In this paper the software has been checked for the cases of oblique incidence as well as of microrelief period and thickness. Copyright © 2014 Taylor & Francis Group, LLC.
