集成光学环形谐振腔研究进展

he miniaturization, integration and large-scale is the goal of integrated optical systems and devices. Ring resonator has become one of the current research hotspots since it has the advantages of small size, low cost, high quality factor, stable performance and simple structure. Ring resonator can be widely used in the fields of optical communication and sensors. This paper discusses the working principle of ring resonator and focus on analyzing several typical and new structures. Then, the preparation process is introduced. Finally, the application of ring resonator is discussed.
