All Optical Wavelength Conversion by Four Wavelength Mixing in Highly Nonlinear Fibers for 160 Gbit/s Phase Modulated Signals

Future optical networks has to be flexible with respect to modulation format, data rate and channel wavelength. Therefore all optical wavelength converters, which do not limit data rates and do not disturb amplitude and phase information, are thought to be key components of next generation networks. The four wavelength mixing (FWM) in highly nonlinear fibers is an efficient process, which could be used for this application. The optimization of the FWM for wavelength conversion regarding low phase error and high conversion efficiency of data signals will be considered in this talk. An transmission experiment of 160 (320) Gbit/s of D(Q)PSK signals is demonstrated.
