Paper Abstract

A novel all-optical wavelength converter for nonreturn-to-zero systems based on a nonlinear polarization switch (NPS) and a delayed interferometer (DI) is proposed and demonstrated experimentally. The performance of the proposed wavelength converter is compared with the performance of a conventional wavelength converter that only incorporates a NPS. Results show that the quality of the converted signal is significantly improved by inserting a DI after the NPS. The transmission performance of the wavelength-converted signal is also improved by the DI.
