Exploring frequency effects in chaotic semiconductor laser

Abstract

Abstract The issue related to the chaos control in semiconductor laser has drew attention. The resonant perturbations have been of high importance with regard to the harnessing non-linear oscillators for different applications including inducing chaos as well as controlling chaos. Interesting results have been obtained regarding to the effect of the chaotic resonance by adding the frequency on the chaotic systems. The forcing frequency changes nonlinear dynamical system via critical value, there has been transition from periodic attractor to strange attractor. The experimental studying for the evaluation of chaos modulation behavior are considered in the case when frequency related to external perturbation has been changed, whereas the amplitude related to such perturbation has been fixed. This dynamic regarding laser output have been analyzed by time series, the FFT as well as the plot diagram as a result of this data.
