一阶斯托克斯光 光纤环形腔 光纤陀螺 克尔效应 first-order Stokes light fiber-optic ring resonator fiber optic gyro Kerr effect
摘要
针对布里渊光纤环形腔(BFRR)的克尔效应发生机理,首先研究了考虑克尔效应的腔谐振特性,理论推导出一阶斯托克斯出射光强发生光学双稳态的可能性。实验证明,入射光为440 μW 左右时30 m 短腔的一阶斯托克斯光会发生光学双稳态,双稳态的特性和腔耦合器的光强耦合系数及插入损耗有关。然后对布里渊光纤陀螺中的BFRR 克尔效应进行了探讨,重点研究了谐振偏离对于陀螺输出非线性以及动态工作范围的影响。提出了一种全新的双环布里渊光纤陀螺方案,为布里渊光纤陀螺的克尔效应误差抑制提供了一种潜在的解决途径。
Abstract
Based on the mechanism of Kerr effect in Brillouin Fiber-optic Ring Resonator(BFRR), the resonant cavity characteristic is researched theoretically when considering the Kerr effect, in order to get the possibility of occurrence of first-order Stokes light optical bistability. Experiments show that the optical bistability in 30 meters short cavity happens while input light intensity is about 440 μW, and the bistability is related with coupling coefficient and the insertion loss of the cavity coupler. Secondly, the Kerr effect in BFRR of Brillouin Fiber-optic Gyroscope (BFOG) is analyzed, focusing on the influence of resonant deviation on gyroscope nonlinear output and dynamic working range. Furthermore, the double-loop BFOG program is proposed, which provides a potential solution of Kerr effect error in Brillouin fiber-optic gyroscope.
