Abstract
The dynamical behavior of two weakly mutually-coupled semiconductor lasers has been recently studied both experimentally and numerically1. The main results predict that two different lasers may synchronize. The simplest synchronization mechanism is such that one laser is forced to oscillate at the relaxation oscillation frequency of the other laser1. On the other hand, experiments on strongly mutually-coupled semiconductor lasers2 show the occurrence of synchronized low frequency fluctuations (LFFs) similar to the ones observed in a diode laser subjected to optical feedback.
