TAPERED LENSED FIBER OPTICAL SWITCH

摘要

An optical switch incorporating MEMS technology and lensed tapered optical fibers achieves less than 0.5 dB in either a thru (cross) or reflected (bar) state. Insertion loss as low as about 0.1 dB in a 2X2 switch in the cross configuration is achieved when anti-reflective coatings are included on the lensed tapered fiber ends. In a particular embodiment a bi-stable MEMS switch with an electro-static comb drive actuator is used.
