Abstract: Integrated mechanical angular alignment-enhancement structures for incorporation into free-space micromachined optical switches are capable of achieving better than 0.1null micro-mirror angular precision and repeatability with the optical switches. The structures open the path to high port-count crossconnects with sufficiently low loss for deployment in practical optical-communications networks.

Abstract: An optical switch device redirects a beam of light traveling along a first direction to a second direction and includes a base member, a reflective panel and an actuator. The reflective panel is pivotally connected to the base member and moves between a reflective state and a non-reflective state. In the reflective state, the reflective panel is disposed to redirect the beam of light from the first direction to the second direction. In the non-reflective state, the reflective panel is disposed to permit the light beam to travel along the first direction. The actuator is connected to the base member and the reflective panel and is operative to cause the reflective panel to move to and between the reflective state and the non-reflective state. An array of optical switch devices can be arranged to form a free-space optical matrix crossconnect apparatus.
