M x N OPTICAL CROSS-CONNECT

摘要

An optical cross-connect is provided which includes an M quantity of first waveguides and an N quantity of second waveguides. The second waveguides intersecting the first waveguides with a node being defined at each intersection. At least one switching element (preferably an oval resonator) is disposed adjacent to each of the nodes to selectively transfer portions of the signals between the waveguides. To minimize cross-talk between the signals, the waveguides are enlarged at, and in proximity to, the nodes to reduce diffraction of the signals.
