We theoretically investigate steady-state behaviors of carbon nanotube quantum dots with spin-orbit coupling in a unidirectional ring cavity. Our results show that the spin-orbit coupling can induce optical bistability. In addition to the existence of spin-orbit coupling, switching optical bistability to optical multistability or vice versa is realized by adjusting detuning of the probe field. Our results show that the carbon nanotube quantum dots will possibly be a promising candidate for realizing all-optical switching.
我们从理论上研究了具有自旋轨道耦合的碳纳米管量子点在单向环形腔中的稳态行为。我们的结果表明，自旋轨道耦合可诱导光学双稳性。除了自旋轨道耦合的存在外，通过调节探测场的失谐可实现光学双稳性向光学多稳性的转换或反之。我们的结果表明，碳纳米管量子点可能是实现全光开关的一个有前途的候选者。
