  • Low loss optical switch using dual axis piezo actuation and sensing
    Patent number: 6836589
    Abstract: Apparatus for producing a collimated light beam within an optical switch, the apparatus comprising: a supporting structure having a first actuator and a second actuator, the first actuator being selectively adjustable along a first plane, and the second actuator being selectively adjustable along a second plane; a fiber optic line having a terminal end to emit a light beam therefrom, the terminal end of the fiber optic line being supported by the first actuator, whereby adjustment of the first actuator repositions the terminal end of the fiber optic line; and a collimator lens being supported by the second actuator, whereby adjustment of the second actuator repositions the collimator lens; wherein at least one of the terminal end of the fiber optic line and collimator lens is repositioned relative to the other one so as to position the light beam emitted by the terminal end of the fiber optic line through a given location of through the collimator lens, which in turn produces the collimated light beam within
