Timing-jitter measurements in optically generated subpicosecond pulses by a quantum-dash passively
mode-locked semiconductor laser as a function of the bias current are reported. All the measurements are
retrieved from a second-harmonic-generation frequency-resolved optical gating system. A decreasing trend
in the pulse width and the associated timing jitter is found with the bias current. Additionally, the optical
and mode-beating linewidths are analyzed in terms of both the mode wavelength and the bias current. From
our results, we can conclude that once the optical modes are phase-locked, the optical linewidth associated
to every individual longitudinal mode of the device under test does not have a significant impact on the
mode-beating signal on neither the pulse width nor its respective timing jitter.
