Paper Abstract

We analyze the all-optical wavelength converter (AOWC) based on a single-port-coupled (SPC) semiconductor optical amplifier (SOA). A comprehensive dynamic model is developed by considering longitudinal variations of carrier density, the residual rear-facet reflectivity of SOA and wide-band spontaneous noise emission (ASE). The numerical simulations for the novel wavelength conversion at 10Gbit/s are presented based on the model. The impact of the rear facet reflectivity on extinction ratio and conversion efficiency is analyzed. We find that when the reflectivity is in the range of 0.2 and 0.3, the extinction ratio over 10dB and the conversion efficiency over 0dB can be achieved. The pattern effect is also discussed to optimize the reflectivity. The wavelength conversion experiments employing two single-port-coupled SOAs with different reflectivity are demonstrated. The extinction ratio and conversion efficiency are measured. The experimental results are agreement with the simulation results.
