1. An apparatus comprising:

  • a plurality of optical ports including at least one input optical port for receiving at least one wavelength channel and at least one output optical port;

    for each optical port, a respective dispersive element optically connected to the optical port;

    a bulk optical element having optical power;

    a plurality of non-transmissive routing elements;

    wherein for each wavelength channel;

    the dispersive element of the input port and the bulk optical element disperses any light of the wavelength channel towards a respective one of said plurality of routing elements, and the respective one of said plurality of routing elements directs the light of the wavelength channel via the bulk optical element to a selected output port of said at least one output port via the respective dispersive element of the selected output port, the selected output port being determined by the respective routing element.
