3. 40 Gb/s Multi-Wavelength Conversion Based on Nonlinear Effects in HNLFMotivation • Current optical networks perform multicasting in network nodes in costly high-speed O-E-O transponders • All-optical wavelength conversion (WC) is an attractive technology for WDM multicasting • Optical multicasting is an important issue in optical grid networks • Several methods for all-optical WC has been demonstrated based on cross-absorption in EA modulators, delay interferometers in SOA, FWM in SOA, pulsed pumped parametric amplification and slicing of SC generated in HNLF CEF workshop, Prague, Czech Republic

13. 40 Gb/s Multi-Wavelength Conversion Based on Nonlinear Effects in HNLFConclusions We investigated, both experimentally and by numerical simulation, all-optical multi-wavelength conversion of 10 Gb/s NRZ signals based on 2-pumps FWM 10 Gb/s and 40 Gb/s RZ all-optical multi-casting system was based on slicing the supercontinuum generated in HNLF. Simulations were performed with OptSim 3.5 and reasonable quantitative agreement between experimental and numerical results was achieved using realistic data given by the HNLF manufacturer CEF workshop, Prague, Czech Republic
