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.
Highlights
The results of numerical simulation of new schemes of compact modal LC spatial modulators are presented
In this paper we present new schemes of compact modal LC light modulators which can form certain types of vortex light fields
Since only a few control electrodes and low control voltages are used in modal LC devices they are easy to control, have relatively low cost and are easy to manufacture
Summary
The results of numerical simulation of new schemes of compact modal LC spatial modulators are presented. Formation of light fields with various (arbitrary) intensity distributions and dynamic control of their parameters is possible using multi-pixel LC SLM. For practical applications the reducing cost of modulators as well as the simplification and reducing the sizes of the optical schemes on their base are of interest. In this paper we present new schemes of compact modal LC light modulators which can form certain types of vortex light fields.
