Abstract
An optical switch having a fiber/lens array and a switching substrate may be properly aligned using one or more static mirrors or photodetectors provided on the switching substrate. The static mirrors may be designed to reflect incident light back into an input fiber, where the back reflected light may be detected, or to a detector provided at a predetermined position. Accordingly, the position of the switching substrate and/or fiber/lens array may be adjusted until reflected light having predetermined power is detected. In another embodiment, the position of the switching substrate and/or fiber/lens array may be adjusted until predetermined power is detected by the photodetectors provided on the switching substrate.
