Abstract

This paper introduces a compact dynamic polarization-modulation system using Liquid Crystal on Silicon Spatial Light Modulators (LCOS SLM) which can be used for data storage in glass. This new design uses two cascade-connected holograms on a single LCOS SLM in conjunction with a half-wave plate, to modulate multiple linear polarization states and simultaneously and generate desired holographic images. Furthermore, a zero-order suppression method is developed based on a computed holographic lens capable of on-axis and off-axis controls for the compact system to improve the quality of the data storage patterns generated by a laser light in glass.
