N2 - An experimental analysis on the quality of 40-GHz radio-frequency
signals generated by various passively mode-locked semiconductor lasers
is addressed. The analysis is performed considering the frequency
linewidth of 40-GHz optically generated signals and the number of
longitudinal modes selected by the cavity of each laser under study.
Four of these devices are multi-quantum wells InAlGaAs
Fabry-Pérot lasers. They have been engineered to exhibit a
specific number of longitudinal modes: 4, 5, 10, and 22 modes,
respectively. Another device under test is a bulk distributed Bragg
reflector laser exhibiting 3 lasing modes. The last device under study
is a quantum-dash Fabry-Pérot laser characterized by 40 lasing
modes. From our experimental results it appears that, regardless the
nature of the device cavity and active media, the strength of the
passively mode-locked mechanism might be enhanced with the number of
longitudinal modes oscillating into the laser cavity, allowing a
reduction in the frequency linewidth.
