<p>A dense wavelength division multiplexer for the separating an optical signal into optical channels. The dense wavelength division multiplexer (400) includes a mechanism (430, 470) for inputting an optical signal having a plurality of channels; a mechanism (410A, 410B, 420, 450) for separating one or more of the plurality of channels; and a mechanism (460, 480) for outputting the separated plurality of channels along a plurality of optical paths. The mechanism of separating one or more of the plurality of optical channels includes glass blocks (410A, 410B) and a nonlinear interferometer (450). The present invention provides an ease in alignment and a higher tolerance to drifts due to the increase in the width of the pass bands. It may also be easily modified to perform the add/drop function as it separates channels.</p> |
