The dependence of laser linewidth on the laser power without taking into considerations of the laser AM-FM coupling effects, namely the Schawlow-Townes linewidth, can be derived by taking the laser as a self-consistent feedback system. Without employing a full quantum statistical analysis of the semiconductor laser noises, we extend this intuitive approach to include the effects of the laser AM-FM...
Single-section multiple-spatial-mode passively mode-locked Fabry-Perot laser diodes are demonstrated to have resonant modulation responses between the relaxation oscillation resonance and the mode-locking frequency. The effect is attributed to the intra-cavity active spatial mode coupling.
