This paper presents performances of an optical packet switch based on dynamic pump wavelength selection (DPS). The switch uses parametric wavelength converters (PWCs), where the pump wavelengths are dynamically adjusted in each time slot. This is different from the conventional scheme, where the pump wavelength is configured in a static manner. A PWC, which performs multiple wavelength conversion, uses a pump wavelength that can be flexibly chosen to define conversion pairs, which are the wavelengths to be converted and converted wavelengths. Matching scheme, which sets connections between input and output ports, for DPS is introduces to enhance switch performance. The dynamic pump wavelength selection is used to select the pump wavelength for each PWC to maximize the number of wavelength conversion pairs supported. Simulation results show that the DPS outperforms the conventional scheme in term of packet loss rate.
