Abstract

We propose and demonstrate experimentally a scheme for the demodulation of 21.4-Gb/s return-to-zero differential quaternary phase-shift keying signals in packet-switched wavelength routed networks where packets at different wavelengths are arriving to the same demodulator. The idea is based on wavelength conversion, and in the demonstration, all channels were received error-free after wavelength conversion. In a packet arrival emulation, the ability of handling incoming packets at different wavelengths were successfully demonstrated.
