Περίληψη:
Non-linear gain compression is well-known to play an important role in the dynamics of short-pulse generation and propagation in semiconductor lasers. Here, a previously reported delay differential equation model for passively mode-locked semiconductor lasers is enhanced with nonlinear gain compression terms in gain and absorber sections. We report the modified model equations and show the impact in gain/absorption dynamics with respect to the original model. In addition, we perform an extended comparison between the enriched delay differential equation model applied on a ring cavity and a travelling wave model applied on an equivalent Fabry-Perot cavity, highlighting the limits of quantitative and qualitative agreement between the two approaches. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC part of Springer Nature.
