  • Optically addressed spatial light modulator (OASLM) with dielectric mirror comprising layers of amorphous hydrogenated carbon
    Patent number: 7092046
    Abstract: A reflective type liquid crystal optically addressed spatial light modulator has a first transparent substrate (1b), a first transparent electrode (2b) formed on the first transparent substrate (1b) and a photosensitive layer (3) formed on the first transparent electrode, formed from materials including hydrogenated amorphous silicon carbide (a-Si:C:H). A read-out light-blocking layer (4) is formed on top of the photosensor layer (3) and is formed from amorphous hydrogenated carbon (a-C:H). The high reflectance dielectric multilayer mirror (5) is formed on top of the light-blocking layer (4) and can be made of alternating the a-Si:C:H layers with a higher refractive index and the a-C:H layers with lower reflective index. The modulator also has a second transparent substrate (1a), a second transparent electrode (2a) formed on the second transparent substrate (1a), and a liquid crystal layer (8) disposed between the dielectric mirror (5) and the second transparent electrode (2a).
