摘要： An optical switch having a fixed-position concave reflector, a fixed array of optical waveguides facing the concave reflector, said array including n number of input waveguides for transmitting the optical signal into the switch, and m number of output waveguides adapted to receive the optical signal, and a refractive element located between the reflector and the array of optical waveguides having multiple angular positions for selectively coupling one of the n number of input waveguides with one of the m number of output waveguides, the switch further including an actuator connected to the refractive element for moving the refractive element between angular positions.

摘要： A continuously variable fiber optic attenuator 10, particularly for attenuating single mode fibers, has means 20 for supporting a section 25 of an optical fiber 24 substantially along the length of the section 25 and means 22 for bending at least a portion of the supported optical fiber section 25 in a controlled manner for attenuating light passing through the optical fiber 24. Preferably, the support means 20 comprises a deformable support means such as a spring 15 or an elastomeric body 71 for supporting the optical fiber 24 as it is bent. Most preferably, the deformable support means supports a section 25 of optical fiber 24 formed in one or more loops around the deformable support means, and the bending means is a plunger 22 movable to an extended position pressing against the support means 20 to bend portions of the loops of optical fiber 24 in a controlled manner. The fiber optic attenuator 10 of the present invention provides accurate control over the amount of attenuation of the light passing through the fiber 24 without damaging the optical fiber 24 or the signal passing therethrough.
