Abstract:
A wavelength cross-connect comprising:an input port for launching an optical beam into the wavelength cross-connect; dispersive means for spatially separating the optical beam into individual wavelength channels; beam deflecting means optically coupled to the dispersive means for selectively deflecting each of the individual wavelength channels in a predetermined manner; an ATO element for providing angle to offset transformation for each of the deflected wavelength channels; relay means for relaying light corresponding to each of the individual wavelength channels to and from the ATO element; and a plurality of output ports, wherein said wavelength cross-connect is configured for independently switching at least one wavelength channel from the input port to one of the plurality of output ports; wherein the relay means includes first and second cylindrical lenses having a same cylindrical curvature, and wherein the ATO element is a third cylindrical lens having a cylindrical curvature perpendicular to that of the first and second lenses.
