Abstract
An optical cross-connect switch includes a switching mirror, a lens mount for securing an optical fiber collimating lens so that a light path from the optical fiber collimating lens is in an alignment relative to the switching mirror and a second lens, and an actuator. The actuator is connected to the switching mirror. The actuator comprises a flexure, and a mechanical motion amplifier. The switching mirror is attached to the mechanical motion amplifier in a thermally stable manner. Mechanical motion of the actuator is damped using a damping fluid. Repeatability of actuator motion is provided for switching the switching mirror into and out of the light path.
