Packet-by-packet wavelength, time, space-domain contention resolution in an optical-label switching router with 2R regeneration

We demonstrate packet-by-packet contention resolution in wavelength, time, and space domains in an optical-label switching system using tunable wavelength conversion, an arrayed-waveguide grating router, and fiber delay lines. Wavelength conversion by cross-phase modulation provides 2R regeneration to the optical signal.
