160 Gbit/s wavelength converter with 3R-regenerating capability

A 160 Gbit/s all-optical wavelength converter with 3R-regenerating capability is demonstrated. The 3R-wavelength converter uses an optical decision gate based on ultrafast fibre nonlinearity to switch a 160 GHz pulse train by the incoming 160 Gbit/s data signal. A pulse shaper is implemented to reduce the detrimental effect of phase jitter in the decision gate and a fibre-based wavelength shifter for free allocation of the wavelength at the output.
