Semiconductor Spatial Light Modulators.

Abstract

The objective of this research was to evaluate techniques for modulating or switching one beam of light with another. The processes investigated were free carrier Faraday rotation, sensor-controlled optical emission, modulation of magnetic bubble diameter, selective pumping of an excited states in garnet with circularly polarized light, and modulation of optical absorption in silicon by pumping hole states. In the last method a control beam of wavelength was used to modulate the transmission and reflection of a 10.59 micrometer beam. (Author)
