Abstract
To steer a beam in an optical switch, a collimator joined to an optical fiber along a Z-axis is mounted in a gimbal for rocking movement about X and Y axes. A piezoelectric actuator extends along the Z-axis and is symmetric about the fiber. An angular position sensor on the collimator provides feedback for use in steering the beam.
