摘　　要：根据洛伦兹互易定理,在通常的光学系统中,交换信号源和探测器的位置后接收到的光信号不变。这为光路设计和分析带来了方便。在全光通信和量子网络中,需要有效地控制光信号的定向传输以避免反射光对信号的干扰、分离相向传输的光信号等,因此需要只允许光单向传输的非互易器件。以磁光隔离器为背景切入,简单介绍磁光领域的研究现状。重点从有源和无源两个方面对无磁非互易领域的发展进行综述,以展现量子光学在无磁非互易领域的重要应用。According to Lorentz reciprocity theorem,we know that in ordinary optical systems,the received optical signal is unchanged even if the positions of the signal source and the detector are exchanged.This brings us convenience for optical design and analysis.However,in all-optical communication and quantum network,it is necessary to effectively control the directional transmission of optical signals to avoid the interference of reflected light and separate the optical signals transmitted in opposite direction.Therefore,nonreciprocal devices that only allow one-way transmission of light are also essential components.This review starts from the background of the magneto-optical isolators and then briefly introduces the research status of the magneto-optical field.The research focus is the development of magnetic-free nonreciprocity,from both the active and passive aspects,which undoubtedly demonstrates the important role of quantum optics in the field of magnetic-free nonreciprocity.
