Abstract
An apparatus for switching a single optical signal to any one of several outputs. An input collimator transmits an optical signal that is reflected from two mirrors on an optical bench into an output collimator. Between the two mirrors is an actuator that interrupts the optical signal and effects another signal from an end collimator into one mirror and the output collimator. The alignment of the collimators and actuators relative to the optical bench is achieved by actively aligning the elements, which includes monitoring an optical signal passing through the collimator and using the signal as feedback for positioning control.
