Single Section Multi-Spatial-Mode Mode-Locking Semiconductor Lasers
01 January 2007
The analysis of single section multi-spatial-mode mode-locking semiconductor lasers is presented. Coupled mode equations are derived from a "Class A" time domain semiconductor laser equation. In the special case where two spatial modes are considered, the additive pulse mode locking (APM) master equation is recovered and the pulse characteristics can be calculated. The equivalent of a saturable absorber function of other mode locked lasers results from spatial hole burning, the linewidth enhancement factor, and fast gain saturation.
