摘要：

Taking into account ultrafast carrier dynamics, we model 640 Gbit/s wavelength conversion based on nonlinear polarization rotation (NPR) assisted with sideband filtering in a single semiconductor optical amplifier (SOA) and investigate the performance of two types of wavelength conversion schemes: one based only on NPR and the other based on NPR assisted by red-shifted filtering. Simulated results show that the two types of wavelength conversion schemes are achieved with clear open-eye diagrams and have signal regeneration capability at 640 Gbits/s. Simulated analyses also show that the wavelength conversion based on NPR assisted by red-shifted filtering scheme exhibits better performance in terms of wavelength conversion and signal regeneration.
