Abstract
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.
