Abstract
Using universal chaos-geometric and multisystem approach it is studied chaotic dynamics of the nonlinear processes in low- and high dimensional dynamics of a chaos generation in the semiconductor GaAs / GaAlAs laser device with retarded feedback. In order to make modelling chaotic dynamics it has been constructed improved complex system (with chaos-geometric, neural-network, forecasting, etc. blocks) that includes a set of new quantum-dynamic models and partially improved non-linear analysis methods including correlation (dimension D) integral, fractal analysis, average mutual information, false nearest neighbours, Lyapunov exponents (LE), Kolmogorov entropy (KE), power spectrum, surrogate data, nonlinear prediction, predicted trajectories, neural network methods etc. There are theoretically studied scenarios of generating chaos, obtained complete quantitative data on the characteristics of chaotic dynamics and topological and dynamic invariants, including Lyapunov exponents, Kolmogorov entropy, the limit of predictability and others
