Paper Abstract

A new type of spatial light modulator, based on the surface plasmon resonance effect, is proposed and demonstrated. The theory and design of these devices is discussed, as are their special features and performance potential in coherent optical systems. The prototype devices use liquid crystal as the active material, and encouraging results have been obtained for speed (2 ms), contrast (100:1), and resolution (20 μm). Higher performance devices using other structures are proposed; these include multi-quantum-well diodes, Langmuir-Blodgett films, and reversible electroplating cells.
