Magnetooptic spatial light modulator for volumetric digital recording system

A novel reflective magnetooptic spatial light modulator has been fabricated and its dynamic switching testing was investigated. Improvements by a factor of three in pixel switching sensitivity and power consumption could be achieved by the use of a wedge-shaped drive line, compared to the use of a conventional reflective magnetooptic spatial light modulator. Simpler fabrication processes by a factor of two could also be achieved by the use of a drive line which covers most of the surface of the pixel, a non-rectangular channel and a unpatterned insulator layer.
