ABSTRACT:
An apparatus, system, and method for all-optical wavelength add-drop switching are provided. A number of optical ports, including at least one input port and at least one output port, are each optically coupled to a respective dispersive element. When a multichannel optical signal is input through an input port, an optical beam of each channel emerges from the dispersive element at an angle depending upon its wavelength. The beams emerging from the dispersive element pass through a bulk optical element which redirects each beam toward a respective one of a number of routing or switching elements, each of which has been set to redirect the respective beam through the bulk optical element towards a selected dispersive element coupled to a selected output port.
