Abstract
A new type of spatial light modulator has been demonstrated, operating by the surface plasmon resonance effect. Devices have been constructed using nematic liquid crystal as the active material, and the operation of these devices is 50 times faster than the bulk switching of the liquid-crystal cells. We have obtained resolution of 10–20 μm and contrast ratios better than 100:1.Keywords
