P-121: Diffraction on anisotropic substrates with surface microrelief

Development of methods of light utilization enhancement in LCD backlight systems is an urgent task. Besides of usual approaches the light polarization management by diffractive optical elements (DOE) allows formation of beams with different polarization status (e.g., both linear and circular or elliptical). The OAGSM software developed earlier provides calculation of diffraction efficiency for optically anisotropic gratings with periodical surface microrelief. In this paper the software has been checked for the cases of oblique incidence as well as of microrelief variable squeezness and period. The results can be used for designing new efficient backlights.
