Abstract
We present, for the first time, extensive simulation and experimental
characterizations of single SOA-MZI-based multiwavelength conversion (MWC)
of NRZ data at 10 Gb/s and RZ data at 40 Gb/s under various parametric conditions
deploying ITU standard 100- and 200-GHz channel spacing. We analyze, in particular,
the physical performance impairments caused by high-order four-wave mixing
interference. Our simulation results indicate the promising performance of
the MWC up to eight channels with 200-GHz channel spacing. We further experimentally
demonstrate four-channel 10-Gb/s error-free MWC with signal regeneration possibilities
and 40-Gb/s MWC with moderate penalties, based on commercially available integrated
SOA-MZIs. We obtained clear, open converted eye diagrams and achieved negligible
difference in channel performance among all MWC channels at both bit rates.
Our results proved the excellent performance of a simple scheme for various
future network and system applications, such as all-optical wavelength multicast
and grid networking.
