Paper Abstract

We describe the design, fabrication, and performance of the frame-addressed spatial light modulator (FASLM), a frame-updated 128 x 128 deformable mirror device (DMD) spatial light modulator(SLM). This new DMD consists of a 128 x 128 array of mirror elements addressed by an underlying virtual phase CCD array. Each mirror element consists of four cantilever beam mirrors attached to a central pillar, allowing contiguous placement of the elements. The FASLM operates at higher speed (up to 4-kHz frame rate with 100% pixel addressing) and with a higher optical duty cycle (96%) than previous DMD SLMs.
