Abstract :
We report on a novel surface-micromachined free-space fiber optic switch with integrated microactuators for optical fiber communication systems. The switch consists of an out-of-plane micromirror driven by integrated scratch drive actuators, and balanced by a spring. A fall time and a rise time of 15 ms and 6 ms have been achieved, respectively. The switch is equipped with the fail-safe feature as required by the FDDI optical bypass switch. In addition, a vibration g-test has been conducted while the switch is transmitting data. Error free operation up to 89 g´s has been achieved for vibration frequencies from 200 Hz to 10 kHz
