Pulse generation from a mode-locked single-section 1.55 mum quantum-dash FP laser is demonstrated under continuous-wave operation. A 270 GHz, 580 fs pulse train is achieved by applying frequency multiplication using fiber dispersion.
An integrated 1300 nm QD mode-locked narrow stripe MOPA is shown to generate 10.5 ps Fourier transform limited pulses at 20 GHz. The pulse train has an average power of 46.4 mW and peak powers exceeding 0.31 W.
We demonstrate for the first time the low penalty cascaded performance of a 1.3mum QD SOA. Eleven passes are feasible for 10Gb/s data while maintaining a Q-factor exceeding 6 for filter-free operation.
