A gimbal for supporting a moveable mirror includes an attachment section, first and second pairs of beams extending along the x-axis and connected to the attachment section, and third and fourth pairs of beams extending along the y-axis connected with the first and second pair of beams. The connections are such that the mirror can tilt or rotate about both the x-axis and y-axis. 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.

Gimbal for supporting a moveable mirror

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).

Photonic switching apparatus for optical communication network

An actuator for tilting a moveable object such as a mirror includes a base and a coil-object assembly that includes first and second pairs of coils each of which is attached to the object, the first pair of coils being arranged along a longitudinal axis, and the second pair of coils being arranged along a transverse axis substantially orthogonal to the longitudinal axis. A gimbal has an attachment section attached to the object, and mounting sections connected via a plurality of beams to the attachment section, the mounting sections being attached to the base. A permanent magnet is positioned adjacent a corresponding one of each of the coils such that when current flows through the coils a rotational force is generated that causes the coil-object assembly to rotate about an axis. 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.
