Controlling Hyperradiance from Chaotic soliton oscillator in Josephson Junctions

Using direct perturbation technology we study how to control the hyperradiance from chaotic soliton oscillator in two weakly coupled long Josephson junctions, by adjusting the bias current. The results reveal that the single soliton in a junction perturbed by a periodic solution of another junction possesses chaotic behavior. When the soliton is approximately synchronized with the periodic solution, the emitted power from the system rapidly increases. Although the boundedness conditions limit its maximal value, the chaotic soliton oscillator may emit much greater power than the soliton pair. Theoretical analysis and numerical simulation both demonstrate the results.
