Abstract: In one embodiment, a method for multi-wavelength encoding includes receiving an input optical packet stream having an address and data and encoding the address of the input optical packet stream producing an encoded address including a first group of symbols including a first selected symbol, where the first group of symbols has more than two symbols. The method also includes generating a first wavelength in accordance with the first selected symbol and generating an output optical packet stream having the data of the input optical packet and the first wavelength, where the first wavelength corresponds to the first selected symbol. Additionally, the method includes modulating the first wavelength with the input optical packet stream.
