Paper Abstract

The Microchannel Spatial Light Modulator (MSLM) is a relatively new, highly sensitive, optically-addressed light modulator that is being developed for low-level-light, real-time, optical information processing. This Paper presents an update of recent progress on the development of the MSLM. Vacuum-sealed and demountable devices employing electro-optic crystals of LiTaO3 and LiNbO3 respectively, are evaluated. These devices are found to have similar characteristics. A halfwave exposure sensitivity of 8.4 nJ/cm2 and a long-term optical information storage time of more than two weeks have been demonstrated with the vacuum-sealed LiTaO3 device; the demountable LiNbO3 MSLM has been cycled at 10 frames per second.
