Dynamics of two coupled semiconductor mode-locked lasers — •Jakob Eberhardt, Stefan Meinecke, and Kathy Lüdge — Institut für Theoretische Physik, TU Berlin, Hardenbergstr 36, 10623 Berlin

Passively mode-locked semiconductor lasers are an inexpensive source of short optical pulses at high repetition rates. Networks of mode-locked lasers have received interest due to applications in data communication and metrology and as a possible implementation of novel analog computing schemes [1]. We numerically investigate the dynamics of the simplest network setup, namely two mutually coupled lasers, using a system of delay differential equations [2]. For two non-identical passively mode-locked lasers, we study the stability and synchronisation behaviour of the two lasers in dependence of the laser and coupling parameters and predict regions of stable synchronised mode locking and regions of leap frogging, where the two lasers alternatingly emit pulses at the fundamental repetition frequency.
