A novel design of micromachining-based high speed 1x2 optical switch array is presented. Employing a triangle-shaped micromachined mirror for beam directing, the design achieved a high level integration of multiple switches on a single substrate, significantly shortened switch time to below 1 ms. An array of four 1x2 switches was fabricated and the performance of the switch array prototype was reported, attaining a fast switch time of less than 750us, extremely low cross-talk <-70dB, an insertion loss of between 0.6 and 0.8 dB, and with an overall size of only 60×36×7 mm3. The experimental result was compared with that from a finite element analysis and a good agreement was obtained.
