Spatiotemporal chaos synchronization in two-dimensional lattice arrays of locally coupled lasers

Abstract

Abstract:

The dynamical properties of two-dimensional 3×3 lattice arrays of single-mode lasers are investigated by numerical simulations. The lasers of the array are locally coupled and interacted through their optical fields and accommodated by setting up some certain parameters of lasers. The results of study show that the intensities between some corresponding lasers can reach the state of chaotic synchronization under the rigor suitable parameters, when the distance of the coupled between arbitrary two adjacent lasers is in the proper area, and they also have the characteristics of the chaotic synchronization between the lasers in the situation of minor diagonal or the parallel diagonal with minor diagonal. Through the computations and the analysis of the power spectra and Lyapunov exponents, it can be convinced that the states of the laser system are chaotic.

Key words: nonlinear optics, chaotic synchronization, arrays of lasers, coupled, power spectra, Lyapunov exponent
