Abstract
Modelling laser structures with different active and passive sections has been a challenge for several decades. One particular task is the derivation and evaluation of simplified rate equation models in the framework of semiclassical laser theory [1, 2, 3]. Here we address this issue by using the composite cavity mode approach [2] and the laser-coupling approach [1] for the specific situation of three laterally coupled lasers; see sketch in Figure 1(a). We present a bifurcation analysis for both models, which gives complementary and consistent results about the dynamics of the laser system. Specifically, we uncover the intersting and complicated structure of the cw-emission (phase-locking) regions of the system.
