Generation of 10 GHz optical pulses with very low timing jitter using one section passively mode locked quantum dash based lasers operating at 1.55 µm

Using either single-side-band phase noise spectrum or optical cross-correlation, timing jitter of 500 fs integrated from 150 kHz to 320 MHz has been measured from quantum-dash Fabry-Perot mode-locked lasers exhibiting a record low radiofrequency linewidth of ~850 Hz.
