摘　　要：基于电磁感应透明原理理论研究了金刚石锡空位色心系统的光学双稳特性。研究表明,通过改变系统的参数,即探测场失谐量、耦合场失谐量和强度、合作参数等,可以显著改变系统的量子相干特性,从而可以有效调控该固态系统的光学双稳的阈值。另外,适当地调节耦合激光场的强度,可以实现光学双稳态和多稳态的相互转化。In this work,based on the theory of electromagnetically induced transparency,optical bistability behavior in a diamond tin-vacancy color center system was theoretically investigated.It was found that a change in system parameters,such as the detuning of probe and coupled fields,intensities of the coupled fields,and cooperation parameters,can significantly change the quantum coherence characteristics of the system.This can be used to control the threshold of optical bistability of a solid system.In addition,the mutual transformation of optical bistability and optical multistability can be realized by properly adjusting the intensity of the coupled fields.
