Abstract
An optical echelle grating for use with a switching fabric to provide different wavelength switching assemblies such as an optical cross connect. The single grating receives a plurality of multiplexed input optical signals and provides optical signals corresponding to the individual wavelength channels to a switching fabric. The switching fabric routes the signals corresponding to the wavelength channels appropriately and the signals then propagate to the grating once more and are wavelength multiplexed.
