摘要
保偏光纤(PMF)谐振腔是谐振式光纤陀螺的核心元件, 在谐振腔中由于偏振耦合引起的偏振波动是陀螺的测量误差的主要来源之一, 而PMF偏振主轴旋转90°对接是克服谐振腔偏振波动的有效方法。对90°对接的双耦合器PMF谐振腔的谐振特性和偏振特性进行了理论分析, 采用锯齿波扫描的方法对90°对接的双耦合器PMF谐振腔的谐振特性和偏振特性进行实验研究, 得到理论响应和实验响应曲线。实验测得谐振腔的精细度为24, 谐振深度为0.9615, 两本征偏振态之间的相位间隔为179.65°, 证明了90°对接双耦合器PMF谐振腔的良好偏振特性。
Abstract
Polarization maintaining fiber (PMF) resonator is the core component of a resonator fiber optic gyroscope. Polarization fluctuation induced by polarization coupling in resonator is one of the main sources of gyroscope’s measure error, and 90° docking of fiber polarization axis is an effective way to overcome the polarization fluctuations in resonator. In this paper, resonance characteristics and polarization characteristics of 90° docking in double couplers polarization maintaining fiber resonator are analyzed theoretically to obtain theoretical response curve, then sawtooth scanning method is experimentally used to obtain response curve with 24 finesse, 0.9615 resonant depth and 179.65° phase interval of the two polarization eigenstates. In consequence, good polarization characteristics of 90° docking in double couplers polarization maintaining fiber resonator are proved.
