Studies On Spatiotemporal Chaos Of Photorefractive Ring Oscillators

The photorefractive oscillator is an important structure of nonlinear optics, in symmetry breaking, periodic alternation, bifurcation and chaos is is a typical phenomenon of linear. For the study of spatiotemporal chaos has also some preliminary results, this paper on the photorefractive oscillator spatiotemporal chaos is based on the research and use the coupled to study of photorefractive oscillator of spatiotemporal chaos chaotic synchronizationThe second chapter analyzed the stability of the photorefractive oscillator, as the system parameters change, the photorefractive oscillator through theperiod doubling bifurcation from steady state into chaos, the chaotic state ofthe photorefractive oscillator from several aspects, time series, power spectrumand bifurcation diagram.The third chapter establishes the ring cavity optical oscillator laser oscillation output spatial expansion model, the ring cavity optical oscillator spatiotemporal chaotic dynamic is studied, the spatiotemporal evolution of study on the one dimensional space, Transverse pattern of extended model of the two-dimensional space researchand from symmetry breaking transition to optical spatiotemporal chaos.The fourth chapter of photorefractive oscillation system of mutual coupling stepwas studied, and by using the coupled synchronization realizes spatiotemporal chaos unidirectional ring photorefractive ring oscillator chaotic system ofprecise synchronization, and studied the effect of white noise onspatiotemporal chaotic systems.
