基于光学薄膜群延迟效应的快光陀螺研究

Recently, the effects of fast and slow light have attracted much attenion of research in optics. Fast light enhanced ring laser gyroscope has open up a new direction of research for ultra-high sensitive and miniturized gyro in the future. We will employ optical thin films with huge group delay as novel anomalous dispertion system to construct superluminal ring laser gyroscope and study its properties. The main contents are as following: (1) Design and fabrication of optical thin films with huge group delay, study the effect of group dealy; (2) Theoretical and experimental study of the superluminal ring laser gyro based on multilayer coatings with huge group delay; (3) Research and development of ultra-high sensitive and minituried gyro. The objective of project is to successfully design and deposit optical thin films with proper group delay, to achieve superluminal ring laser gyro, obtain its properties, enhance its sensitivity, finish its miniturization, and explore its application in hypersensitive inertial nevigation and gravitational wave detection. This work is significant for basic research as well as for application.
