Abstract

A transmission-line laser model (TLLM) for mode-locked lasers is modified to include carrier-induced index variations which is the cause of laser chirp. Time-domain dynamic simulations show this to cause pulse narrowing, spectral shifting, and spectral broadening. The effects of AC drive, DC bias, unwanted reflections, and higher-harmonic RF drive are also investigated. The authors present results showing how chirp, drive conditions, facet reflectivity, and harmonic operation affect pulse shape, stability, and pulse spectra
