摘要
通过Rsoft软件对锥形光纤倏逝场能量分布特性进行仿真,从理论上分析锥形光纤激发微谐振腔非互易性产生的原因。实验中,光纤熔融二氧化硅微球腔通过高精度三维调节架沿光纤方向移动,每次移动相同距离选取测试点,记录光源正反传输情况下微球腔谐振谱线,得到谐振谱线特征参量随倏逝场变化的非互易性变化规律。通过计算微球腔理论鉴频曲线获得非互易性对陀螺动态范围与灵敏度的影响,并提出抑制方法。
Based on Rsoft software, the tapered fiber evanescent field distribution is simulated, and the reason for the nonreciprocity of micro- resonator excited by tapered fiber is analyzed in theory. Optical fiber fused silica microsphere cavity is used in the experiment. Through high precision three dimensional adjustment along the fiber direction, test points are selected after moving the same distance and microsphere cavity resonance spectra are recorded under the case of forward and converse transmission of light, getting the regular pattern of non-reciprocity of the resonance spectral parameters with the variation of evanescent field.By calculating the frequency discrimination curve of microsphere cavity, the influence of non- reciprocity on the dynamic range and sensitivity of gyroscope is got, and suppression methods are proposed.
