摘　　要：研究了光学环形腔中的单方向传输光在光学谐振腔中传输的情况 ,在系统旋转角速率变化时光束会产生频移 ,在此基础上 ,设计出一种具有谐振腔马赫曾德尔干涉集成光波导陀螺结构 ,可以方便地检测出系统旋转角速率与方向 ,其检测精度与光波导谐振腔的品质无关。和萨尼亚克集成光波导陀螺相比较 ,性能价格比有进一步提高的潜力。A theoretical study on the propagation of single direction light in optical ring is presented. When the angular velocity changes, the frequency of single direction light propagating in optical ring will shift. The analytical expressions are obtained for the resonance conditions when the light propagates in optical ring resonator. A kind of integrated optical waveguide gyroscope structure based on ring resonator and Mach Zehnder interference is designed, which provides a convenient way to sense both the angular velocity and rotational direction. And the precision of such gyroscope is independent of the finesse of optical waveguide ring resonator. Comparing with the optical waveguide ring resonator based on Sagnac effect, this kind of structure has potential to get better performance.
