Abstract
We demonstrate multihop optical code labeled packet switching with agile and phase-preserved wavelength conversion. The wavelength converter consists of a highly-nonlinear fiber (HNLF) and a multiwavelength distributed feedback laser-diode (DFB-LD) array module. We obtained a switching time of less than 1 ns, and the tolerance of the optical encoder for wavelength shift of the DFB-LD was 0.08 nm. The relative phases of each chip pulse in eight-chip-long binary phase shift keying (BPSK) optical code after the wavelength conversion by four-wave mixing (FWM) is preserved. We simulate the performance of packet-loss probability with the wavelength conversion in a limited wavelength range of the wavelength converter. The numerical simulations show that the packet-loss probability degrades only 3.1% under the link utilization of 0.4, in comparison to that with the wavelength conversion having an unlimited wavelength range of conversion.
