    摘要： An all-optical switch includes an array of input optical fibers and an array of output optical fibers. A rhomboidal prism beam splitter is positioned in operative relationship with the array of input fibers such that when an array of optical beams is propagated from the array of input optical fibers, the beam splitter splits the array of optical beams into a signal path and a tap path. The rhomboidal prism beam splitter includes a partial internal reflection (PIR) surface and a total internal reflection (TIR) surface. The PIR surface and the TIR surface cooperate to split the array of optical beams into the signal path and the tap path such that the signal path is substantially parallel to the tap path upon exiting the beam splitter.

    摘要： An optical switch embodiment includes a switching array of arranged to accomplish switching of input light beams to any of a plurality of output channels and an array of beam monitoring elements for indirectly measuring and providing information used for adjusting output beams. The beam monitoring element further includes means for measuring the angular misalignment and the positional misalignment of a monitor beam and adjusting the reflectors based on monitor beam information such that optical beams are output from the switch having the desired optical characteristics, such as optimized power. Another optical switch embodiment includes an array of rhomboid prism assemblies positioned to receive the output beams from the switching array and such that the beams are split into substantially parallel working and monitor beams. Whereby the working beams pass into the plurality of output channels and the monitor beams pass into the plurality of beam monitoring elements where they are measured to provide information for adjusting the angular misalignment and the positional misalignment of the working beam.
