    摘要： Optical switch packaging techniques and optical switch components are described. In one aspect, an optical switch component that includes a die mounted on an interposer is described. The die has an exposed array of mirrors that can be used as part of an optical switch. Typically, the interposer will also have a fiber array mount arranged to receive a fiber bundle and to position the fiber bundle appropriately over the array of mirrors. In some embodiments, an optical switch can be formed by putting together two mirror image interposer based optical switch components. When placing two interposer based optical switch components together, an alignment frame may be positioned between the interposers to help maintain a desired spacing between the respective arrays of mirrors. In some such embodiments, an inner housing is provided that encloses the dice, the fiber array mounts the alignment frame and portions of the interposers, but leaves connectors mounted on the interposers exposed. An outer housing may optionally be provided to encase the optical switch components and the inner housing. A resilient filler material may also be provided between the inner and outer housings to provide additional protection to the optical switch.

    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.
