The system includes a plurality of identical switch blocks, each of is formed in a different reticle field that no larger than the maximum reticle size. Bus waveguides of laterally adjacent switch blocks are stitched together at lateral interfaces that include a second arrangement of waveguide ports that is common to all lateral interfaces. Bus waveguides of vertically adjacent switch blocks are stitched together at vertical interfaces that include a first arrangement of waveguide ports that is common to all vertical interfaces. In some embodiments, the lateral and vertical interfaces include waveguide ports having waveguide coupling regions that are configured to mitigate optical loss due to stitching error.

摘要： Methods and systems for generating a laser beam with different beam profile characteristics are provided. In one aspect, a method includes coupling an input laser beam into one fiber end of a multi-clad fiber, in particular a double-clad fiber and emitting an output laser beam from the other fiber end of the multi-clad fiber. To generate different beam profile characteristics of the output laser beam, the input laser beam is electively coupled either at least into the inner fiber core of the multi-clad fiber or at least into at least one outer ring core of the multi-clad fiber, or a first sub-beam of the input laser beam is coupled into at least into the inner fiber core of the multi-clad fiber and a second, different sub-beam of the input laser beam is coupled at least into the at least one outer ring core of the multi-clad fiber.

摘要： A switch for selectively coupling light from two input fibers to a selected two of plurality of output optical fibers. The switch was designed to handle standard Fiber optical connectors which have been polished and meet the specifications for the optical performance. The duplex mechanical switch creates a method to physically switch two fibers (Duplex) to another two fibers (Duplex). The performance regarding insertion losses, back reflection, crosstalk, immunity against backscattering of light and insensitivity to the wavelength of the light is consistent with this mechanical switch.

摘要： An optical fiber positioner having an elongated base with sidewalls and a longitudinally extending throughbore. A flexible optical fiber extends through the throughbore and has one end protruding outwardly from an end surface of the base. A plurality of actuators are secured to the sidewalls of the base so that an end of each actuator is positioned adjacent the end of the base. A crossbeam is then connected to the ends of each actuator so that the crossbeam moves laterally relative to the base in unison with the deflection of the actuators. The crossbeam has an opening through which the optical fiber extends so that the optical fiber deflects in unison with the lateral movement of the crossbeam. Various fixtures for assembly of the optical fiber positioner are also shown.
