Simultanious generation of pulse trains with different periods in a class C quantum-dot heterolaser

Numerical simulations and qualitative analysis of the predicted simultaneous generation of different quasiperiodic pulse trains [1] - [3] in a CW multimode class C quantum-dot heterolaser with self-locking of some of the modes are carried out on the basis of the Maxwell-Bloch equations. For the class C lasers, a photon (cavity) lifetime is of the order of a lifetime of a polarization (a density of the quantum-dot optical dipoles). We consider the combined low-Q Fabry-Perot cavities with distributed feedback of counter-propagating waves, where higher-Q modes are situated close to the ends of a photonic bandgap and lower-Q quasi-equidistant modes occupy the adjacent wings.
