Abstract: We consider two weakly coupled Josephson junctions. Using usual perturbation technology we discuss the system hyperradiance from soliton perturbed by a periodic sinusoidal wave. The results reveal that soliton with periodic perturbation possesses chaotic behavior. When the soliton is nearly synchronized with periodic solution, the emitted power will rapidly increase. Although the boundedness condition limits its maximal value strictly, chaotic soliton oscillator emits much greater power than soliton pair in general. Theoretical analysis and numerical simulations both demonstrate the above results well. Those results gave theoretical basis for practical application.
