Parametric NRZ-to-RZ wavelength multicasting with pulsewidth tunability using Raman amplification multiwavelength pulse compressor

A novel technique for all-optical 4×10 Gb/s NRZ-to-RZ format conversion and wavelength multicasting with pulsewidth tunability using a Raman amplification-based multiwavelength pulses compressor and a high nonlinear fiber is successfully demonstrated. The input NRZ signal is multicast and converted to RZ signals at four wave mixing products and the pulsewidths follow those of the compressed clocks. The tunable pulsewidth of RZ signals outputs are around from 4.68 ps to 12.17 ps. Error-free operations are achieved with small penalty variations among RZ outputs channels.
