Abstract:
1. An apparatus comprising: a first waveguide array having a plurality of waveguides disposed therein; a second waveguide array having a plurality of waveguides disposed therein, the second waveguide array disposed proximate the first waveguide array and substantially symmetrically disposed on opposite sides of an optical axis of the apparatus as compared to the first waveguide array; at least one light focusing device operable to receive an optical signal to be demultiplexed and to direct the received optical signal to be demultiplexed to a dispersion apparatus aligned therewith, the at least one light focusing device further operable to receive a plurality of optical signals to be multiplexed from the first waveguide array and to direct the received plurality of optical signals to be multiplexed to the dispersion apparatus aligned therewith; the dispersion apparatus operable to disperse the received optical signal to be demultiplexed into a plurality of selected spectral wavelengths and to reflect the selected spectral wavelengths in a plurality of demultiplexed optical signals back to the light focusing device, the dispersion apparatus further operable to combine the received plurality of optical signals to be multiplexed and to reflect the combined multiplexed optical signal back to the light focusing device; and the light focusing device operable to direct the reflected plurality of demultiplexed optical signals to at least the second waveguide array.
