Abstract:
An optical switch for switching light beams between input ports and output ports, comprising:a base; a first input port, a second input port, a first output port, and a second output port all supported by the base; a movable reflector assembly comprising a first reflector and a second reflector being capable of moving up and down between a first position and a second position; and a driving means for switching the movable reflector assembly between the first position and the second position; wherein, in the first position, the light beams propagate from the first input port to the first output port after being reflected by the first reflector and the light beams propagate from the second input port to the second output port after being reflected by the first reflector, and wherein, in the second position, the light beams from the first input port propagate directly to the second output port and the light beams from the second input port propagate to the first output port after being reflected two times by the second reflector.
