Abstract
A photonic switch for an optical communication network includes a matrix of actuator-mirror assemblies and a corresponding matrix of optical ports. A first one of the actuator-mirror assemblies directs a beam of light received from an input optical port to a reference mirror, where it is reflected to a second actuator-mirror assembly that redirects the beam to an output optical port. Each of the actuator-mirror assemblies includes a mirror-coil assembly mounted to a gimbal, with stationary magnets being positioned adjacent a corresponding one of the coils such that when current flows through the coils a force is generated that causes the mirror-coil assembly to tilt. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
