摘要： An optical switch having a fiber/lens array and a switching substrate may be properly aligned using one or more grating(s) provided on the switching substrate. The grating(s) may be designed to have a predetermined response when the fiber/lens array and switching substrate are properly aligned. For example, the grating(s) may reflect incident light back into an input fiber, where the back-reflected light may be detected. Accordingly, the position of the switching substrate and/or fiber/lens array may be adjusted until back reflected light having predetermined power is detected.

摘要： The present invention provides a device and method for achieving protection in a free-space micromachined optical switching fabric. The present invention provides two protection schemes for mirror failures, which utilize either existing switching mirrors or additional integrated mirrors without extra fabrication effort or performance-degradation of the switch fabric. A switch fabric includes a plurality of micromachined free-rotating mirrors arranged in a rectilinear matrix configuration. The mirrors are reflective on both front and back sides. According to one embodiment of the present invention, upon the detection of a failed mirror associated with a transmission between an input and an output, a transmission path is determined that includes a backside of a pivot mirror. A transmission path is then established between the input and the output that utilizes the backside of the pivot mirror.
