Numerical simulation of a large number of coupled lasers

A simulation has been carried out on N coupled lasers. A complex coupling parameter has been used, thus accounting for the phase of the interacting fields; the phase of the coupling parameter turns out to be a key parameter that determines the dynamics of the system. Nonlocal coupling is considered, in which cooperative effects in the oscillator community are emphasized. It is shown that achieving a phase-locked or synchronized state is crucially dependent on the statistical width of the distribution of cavity resonance frequencies and also on the coupling mechanism.
