Abstract

This paper investigates sensitivity of semiconductor lasers to external optical signals. Bifurcation analysis of ordinary rate equations, describing noise-free lasers with pure coherent external signal, reveals that adjusting the extend and type of externally-induced bifurcations and chaos to desired state is possible by tailoring of the laser active medium and resonator configurations. Extending the analysis to stochastic rate equations, which describe lasers with spontaneous emission noise and noisy external signal, reveals a dramatic impact of phase-fluctuations (incoherence) in the external signal on induced bifurcations and chaos. A nonlinear optics approach is proposed where the strong sensitivity of laser instabilities to the intensity and coherence of external signal are used to detect ultra low levels of laser radiation.
