<p><P>PROBLEM TO BE SOLVED: To provide an all-optical 1×N optical switch more easily controllable having lower optical loss and fewer components than a 1×N optical switch of the prior art. <P>SOLUTION: The optical switch of the invention includes an active deflection element formed from an electro-optical material and deflects an optical input from a single input to selected one of N outputs. In one embodiment of the invention, a single active deflection element at the input deflects an optical signal across a waveguide that commonly connects the N outputs. The N optical outputs include passive optical elements aligned with the deflected optical signal so as to accept a signal and to supply the signal to a selected optical output. The optical switch can be either a monolithic switch having the entire optical material made of electro-optical materials, or a hybrid switch having separately formed components such as the common waveguide, adhered to the substrate where the optical switch is formed. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
