An experimental study of the dynamics of a
quantum-dash Fabry-Pérot passively mode-locked laser diode is
presented. Firstly, the switchingon and off characteristic times
of the mode-locking mechanism with pulsed biasing current are
assessed. Secondly, the locking and unlocking characteristic times
to the injection of a 10-Gbps pseudo-random binary sequence of
nonreturn-to-zero data are determined. The dynamics is analysed
through the instantaneous frequency of the 40 GHz beat-tone
signal measured at the output of the laser under investigation,
which after a frequency down-conversion stage, is recorded by a
real-time oscilloscope. Experimental results indicate that a time of
5 ns characterizes the establishment of the passive mode-locking
mechanism for a pulsed biasing current. A time of 20 ns has
been measured for the synchronization of the quantum-dash
laser diode to the injected 10 Gbps data sequence. In addition,
the mode-locked laser diode de-synchronizes and switches to
the free-running condition in also 20 ns after a holding time of ~100ns.
