Nonlinear ring interferometer (NRI) is an open passive optical system. Occurence of various steady spatial structures nad dynamic chaos in cross-section of the laser beam propagating through the NRI feed-back circuit under certain conditions is possible. Therefore investigation of various NRI models is perspective with a view of their application in devices of the optical information processing and the hidden transmission of the information. The NRI can make element basis of the devices of the continual logic.
Implemented numerical experiments are based on the model of processes in nonlinear ring interferometer with Kerr's nonlinearity in the context of optical cryptosystem development. Chaotic regimes area of Lyapunov's exponent's map portion was suggested to be the integral quantitative characteristic of the whole map. It was proposed to construct the distributions of certain type attractor's quantity depending on model's parameters.
Influence of two-frequency input radiation spectrum on bifurcation behavior in the model of ring resonator (interferometer) with restriction of nonlinearity is studied. A bifurcation diagrams in various planes of model parameters are under construction and the degree of influence of these parameters to configuration of (un)steady states of the interferometer functioning is studied.
