Abstract
Non-reciprocal optical devices in integrated systems on a chip have attracted great interest due to the increasing demand for researching integrated photonics and silicon photonics. The non-reciprocal devices include optical isolators, circulators, and optical amplifiers. In this paper, We analyze the dynamic nonreciprocity of an optical isolator based on the principle of electromagnetically induced transparency, and show a comparison of the nonreciprocal transmission when waves are transmitted forward and backward. The results show that when energy is transmitted, this isolator can realize signal isolation with specific direction transmission at non-single frequency. This device can be used in a wide range of signal processing and optical communication applications.
