Abstract :
Taking into account ultra-fast carrier dynamics, we model 640 Gbit/s wavelength conversion based on nonlinear polarization rotation (NPR) in a single semiconductor optical amplifier (SOA) and investigate the performance of three kinds of wavelength conversion schemes: one only based on NPR and the other two based on NPR assisted with sideband filtering. Simulated results show that the three kinds of wavelength conversion schemes are achieved with clear open eye diagrams and have signal regeneration capability at 640 Gbit/s. To further investigate the performance of three kinds of wavelength conversion schemes, the dependence of output extinction ratio (ER) on some key parameters used in simulation is illustrated. Simulated analyses show that the wavelength conversion based on NPR assisted with blue-shifted filtering scheme exhibits the best performance in terms of the maximum output ER for wavelength conversion and the maximum dynamic range of input power for signal regeneration.
