ABSTRACT:
A micro-opto-electromechanical systems (MOEMS) device comprises a micro-electromechanical systems (MEMS) device and a silicon optical-bench (SiOB) device or system. The MEMS device interacts with the SiOB mechanically or electromagnetically. In one embodiment, the MEMS device is operable to provide a switching function for the SiOB device. The MEMS device comprises an actuator that is mechanically linked to an optical interruptor that prevents at least a portion of an optical signal incident thereon from propagating therethrough. In an actuated state, the actuator causes the optical interrupter to move into an optical path of an optical signal traveling through an SiOB device. The signal is at least partially reflected or absorbed such that only a portion of the signal propagates beyond the point of contact with the optical interrupter. Since SiOB processing is typically incompatible with MEMS device processing, the MEMS and SiOB devices are formed on separate supports and then attached, such as via flip-chip bonding methods.
