Paper Abstract
The chaotic behavior of on external-cavity semiconductor laser (ECSL) working in a regime of low-frequency
fluctuations (LFFs) can be controlled by external electro-optical phase or intensity current modulation. It is shown by
numerical simulation that, for specific values of the modulating frequency and amplitude, the phase difference between
the laser power drop-out and the modulator remains constant in time leading to phase-synchronized states, steady LFFs,
so called m:n phase synchronization. The degree of stabilization is determined by calculating Shannon's entropy and by
the analyzing the stability of the phase locking. The synchronization regions are mapped and zones of low and high
amplitude chaos are identified. The light emission can be stabilized from a regime of large amplitude chaotic oscillations
corresponding to LFFs to one of low-amplitude chaotic or even periodic oscillations. The dynamics of the laser can be
controlled when the period of the modulating signal is comparable with the laser itinerancy time between consecutive
external-cavity modes.
