E-Beam Addressed Spatial Light Modulator Employing Electron Trapping Materials. Phase 1.

Abstract

Spatial light modulators (SLMs) play a critically important role in optical signal processing optical computing. A novel electron beam addressed emissive SLM which combines high performance polycrystalline electron trapping (ET) materials with an advanced field-emitter array is being developed. The proposed SLM combines high resolution (> 100 lplmm), high SBP (> 1000x1000), high frame rate (>- 1 KHz), high contrast ratio (> l03:l) and low drive voltage (< 15 V) in a single device. The additional features of the proposed SLM are its wide variety of operation modes and electrical and optical dual-addressability. Such a SLM, if successfully developed, will surely have substantial impact on optical processing technology. During the Phase I efforts, a review of field emitter arrays has been done to show that it has the merits of electrical-addressability, high space- bandwidth product (SBP), low drive voltage compatible with IC driving circuitry, and high update speed. The device architecture has been investigated and the design of two prototype devices has been provided.
