Abstract :
A proposed improvement of the nonlinear tolerance in 40 Gbit/s optical transmission by applying a 10 GHz phase modulation is presented. The improvement is obtained because intra-channel four-wave mixing (IFWM) is suppressed. It is shown, both by numerical simulations and experiments, that the penalty induced by IFWM is significantly reduced.
