摘要：

We study spontaneous symmetry breaking in a dual-core system with a rotating double well potential in self-focusing nonlinearity. By tuning the coupling parameter and total optical power, four types of mode have been found. Double symmetry breaking, which is a combination of the symmetry breaking of the waveform and the optical power distribution, occurs under specific conditions. The numerical simulations show that there are some overlaps among the different stable modes, which have confirmed the coexistence of the modes. It is found that the region where the four stable modes coexist shifts with the variation in the rotating speed, and the corresponding parameters, the coupling parameter and total power, decrease sharply with the increase in the rotating speed.
