Abstract
A system for processing an optical signal includes a reflector that reflects an input optical signal to a selected one of a number of output waveguides and reflects a reference optical signal associated with the input optical signal. A detector detects a position coordinate of the reference optical signal. A memory coupled to the detector stores an expected position coordinate for the reference optical signal. A controller coupled to the memory generates a control signal based upon the position coordinate detected by the detector and the expected position coordinate stored in the memory. An actuator coupled to the reflector positions the reflector in response to the control signal.
