New schemes of compact modal LC modulators for control of light spatial structure

Abstract

The results of numerical simulation of new schemes of compact modal LC spatial modulators are presented. Special configurations of contact electrodes and predetermined values of applied voltages provide the jump in the profile of phase delay of light passing through the modulator or reflecting from it. This leads to the appearance of a vortex field. Ring-shaped light fields and light fields with intensity distribution in the form of two maxima, which rotate in the transverse plane during propagation were obtained. These devices may be valuable for use in the spectroscopy of single molecules.
