Design and implementation of erbium-doped fiber laser chaotic circuit

In order to study the dynamics characteristic of dual-ring erbium-doped fiber lasers, the simulation method of designing a circuit using individual electronic components is proposed. This circuit is able to exhibit its chaotic behavior. Based on the equations of its dynamics system, the circuit simulation and hardware test results are obtained by transforming its coefficients and circuit design accordingly. By regulating the variable resistor of circuit in the experiment, the chaotic orbit could be adjusted with different orbiting periods. The result is consistent with dynamics analysis oferbium-doped fiber dual-ring laser. The applied circuit has good capability ofsimulating the dynamics ofthe dual-ring erbium-doped fiber lasers. In addition, the experiments show coherent results with the theoretical analysis.
