Abstract

This paper reports our studies of a novel erbium-doped (ED) fiber inter-coupling three-ring laser (TR-L) system, where three ED fiber single-ring lasers are inter-coupled by three couplers to form this kind of laser. Thereout, our work establishes the laser physical theory of the TR-L system, and studies its bifurcation behavior in detail. The dynamical behavior evolving from a steady behavior through a double-period to a chaotic behavior is introduced via phase parametrization to reveal a path to some chaotic behaviors from double-period to pass through some quasi-periodic bifurcations by shifting one parameter of the laser. Numerical phase-parametric diagrams exhibit quasi-period bifurcation via adjusting the pump strength or the ring coupling levels. The chaotic region and quasi-period bifurcation region are found. Period-one, quasi-period, and chaos are numerically presented to show rich nonlinear dynamic phenomena. The fiber laser gives an important value to study laser systems, chaotic optics emitters, random optics signal generators, measuring devices, and encoding communications.
