ABSTRACT:
A device for shifting the phase of light propagating through an optical fr, comprising a microbend transducer to bend the optical fiber. The microbend transducer comprises first and second transducer blocks each having a set of teeth positioned so that they face each other with a passageway therebetween through which the optical fiber passes and is bent by them. A device for modulating the intensity of light propagating through an optical fiber which has two tapered ends, comprising first and second mode strippers each operably attached to one of the tapered ends of the optical fiber and a microbend transducer disposed to bend the optical fiber.
