摘要
针对泵浦偏振态对高精度光纤陀螺掺铒光纤光源平均波长稳定性产生影响的问题,设计了掺铒光纤光源泵浦消偏的结构,该结构采用 Lyot光纤消偏器来对泵浦光进行消偏,理论分析了该结构中 Lyot消偏器结构参数的选取。实验验证了掺铒光纤光源的波分复用器具有偏振特性,会影响掺铒光纤光源平均波长稳定性,采用设计的泵浦消偏结构可有效消除波分复用器具有的偏振特性。在光源结构已被优化,只考虑泵浦偏振态对光源平均波长稳定性影响的情况下,对温箱中的光源进行对比实验,结果表明,对偏振态未加任何控制的掺铒光纤光源平均波长稳定性为 77 ppm,采用泵浦消偏结构的光源平均波长稳定性为 4 ppm,即本文设计的泵浦完全消偏结构使得掺铒光纤光源平均波长稳定性得到了显著提高。
Abstract
Depolarization pump structure of Erbium Doped Fiber Source(EDFS) is designed to solve the problem that polarization state of pump influences high precision EDFS average wavelength stability for Fiber Optic Gyroscope (FOG). This structure is adopted to Lyot depolarizer to depolarize pump light, and the Lyot depolarizer parameters selection is analyzed theoretically in the design construction. Experimental results prove that the polarization property of Wavelength Division Multiplex (WDM) affects the EDFS average wavelength stability, and the design structure can effectively reduce polarization property of WDM. When EDFS parameters have been optimized, considering that the pump of polarization state influence EDFS average wavelength stability, measure EDFS in the temperature cabinet. Experimental results show that without control polarization state, EDFS average wavelength stability is 77 ppm, while, adopting the structure of pump light complete depolarization, EDFS average wavelength stability is enhanced to 4 ppm.
