研究了低能级偶极子的非相干泵浦过程对环形腔中双稳行为的影响。结果表明，耦合系统的双稳机制为非相干泵浦过程的干涉性。双稳迟滞环与非相干泵浦场有严格的对应关系，在一定条件下，甚至出现多稳态。可以利用非相干泵浦的干涉性控制光学双稳。 The effect of incoherent pumping of low-energy dipoles on bistability in a toroidal cavity is investigated. The results show that the bistable mechanism of the coupling system is the interference of the incoherent pumping process. Bistable hysteresis loop and non-coherent pump field has a strict correspondence, under certain conditions, even multi-stable. Optical coherence can be controlled using the interference of incoherent pumping.
