Single crystal silicon (SCS) micromirror arrays using deep silicon etching and IR alignment
10/spl times/10 and 5/spl times/5, a high mirror fill factor (>70%), low voltage operation (<30 V), single crystal silicon (SCS) micromirror arrays have been designed, fabricated, and tested. Each mirror is 320 /spl mu/m by 170 /spl mu/m and is individually addressable. In comparison to thin film micro-mirror arrays, the SCS mirror surface is optically flat and smooth, free of residual stress, and highly reflective after the deposition of a thin aluminum layer. In addition to a flat mirror, high-aspect-ratio grating structures have been fabricated on the surface of the mirrors, enhancing the optical manipulation potential of devices.
