Abstract

An N×N optical switching array device and system are disclosed. In one aspect, an optical switching device for communicating optical signals is provided. The device includes a plurality of optical inputs operable to communicate optical signals, a plurality of optical outputs optically coupled to the optical inputs and at least one thermo-optic array optically coupled to the plurality of optical inputs and the plurality of optical outputs. The device further includes an thermo-optical array operable to deflect an optical signal from one of the plurality of optical inputs to one of the plurality of optical outputs in response to a temperature differential.
