In this work, we investigate the generation of 20 and 40 GHz pulse trains by nonlinear compression of an initial beating in a cavity-less optical-fiber-based configuration. High temporal stability is obtained by generating the sinusoidal beating by means of an intensity modulator driven by an external clock. The residual timing jitter induced by the RF phase modulation is then reduced by managing the cumulated dispersion of the compression line whereas complete polarization stabilization is obtained thanks to a modified setup including a Faraday rotator mirror. Finally a high-quality 160 Gbit/s signal is generated from our low duty-cycle 40 GHz pulse source thanks to optical time domain multiplexing.
