Abstract
Multiple wavelength conversion is very important for improving the flexibility of wavelength division multiplexing optical networks. A 410 Gbit/s all optical wavelength conversion is demonstrated based on multiple four-wave mixing in high nonlinear photonic crystal fiber. The impact of parameter variation such as pump power, fiber length and polarization state on wavelength converted signal quality is investigated. The simulation results show that the Q factor of converted signal increases with the increasing of the pump power (from 6 dBm to 20 dBm) and the fiber length (from 50 m to 120 m), and the maximum Q factor is 82.01 and 57.41, respectively. Furthermore, the Q factor of converted signal decreases with the increasing of the polarization mismatch angle, and the Q factor decreases rapidly especially when the polarization mismatch angle is more than 60.
