Abstract:
1. A method for routing optical packets using each of multiple wavelength labels, comprising: executing on each packet a first operation to impart a wavelength dependent delay time to a plurality of optical pulses having different wavelengths at a same time axis position, said first operation resulting in conversion of optical packet address signals to a plurality of optical pulses having different wavelengths and having deviated time axis positions; transmitting the plurality of optical pulses along a predetermined optical path and, when the optical path has dispersion, compensating for said dispersion; executing a second operation on the optical pulses corresponding to a reverse process of said first operation, said second operation resulting in generation of a plurality of optical pulses having different wavelengths at a same time axis position; and using signals of the plurality of optical pulses thus generated to determine a transmission route.
