Abstract A novel 40Gbit/s reamplified-reshaping-retiming (3R) regenerator is proposed and demonstrated based on a two-ring injection mode-locked fibre laser as the clock recovery and the electro-absorption modulator of the reshaping optical decision. A numerical model describing the cross-absorption modulation effect in a bulk electroabsorption modulator is presented. By this model, the shape and the extinction ratio of the optical decision gate is improved by optimizing the parameters. The polarization mode dispersion mitigation by the 3R regenerator is experimentally demonstrated at 40Gbit/s with improved bit-error-rate (BER) performance when the differential-time-delay value is set up to 40% of bit interval.
