摘要

The design and development of a microelectromechanical, micromachined spatial light modulator (μSLM) with complementary metal-oxide semiconductor (CMOS) electronics, for control of optical phase in phase-only optical correlators is presented in this paper. A large array of piston-motion MEMS mirror segments make up the μSLM. Each mirror segment will be capable of altering the phase of reflected light by up to one wavelength for infrared illumination (λ = 1.5 μm). The mirror segments, or pixels, are fabricated from metal in a low temperature process allowing for vertical integration of the μSLM with CMOS based, 8-bit, control electronics. Proof-of-concept results, a proposed fabrication process and, preliminary process development results are also presented.
