Paper Abstract

Detailed description of the structure, operation, fabrication, and performance of a fast-response metal-insulator-semiconductor structure mono-crystalline gallium arsenide as photo-addressing medium for infrared liquid crystal spatial light modulator (GaAs-IR-SLM) is reported. A GaAs-IR-SLM is demonstrated with a limiting resolution of 20 lp/mm over a 40 mm aperture and contrast ratios of greater than 20:1 in the 8 to approximately 12 μm wavelength.
