分析给出了保偏光纤截止波长测量的实现方法,通过解决可变波长单色偏振光产生技术和测量过程中保偏光纤的对轴耦合技术,研究建立了保偏光纤截止波长校准装置,分析验证了测量结果和装置的性能,为统一保偏光纤截止波长参数量值奠定了基础。

The measuring method of polarization-maintaining optical fiber cutoff wavelength has been presented by analysis. We establish the calibration device for polarization-maintaining optical fiber cutoff wavelength by figuring out the generation technique of variable-wavelength monochrome polarized light and the countershaft-coupling technique of the polarization-maintaining optical fiber during the meas- urement. The measuring result and device performance have been verified by analysis. These studies es- tablished the foundation for the unification of quantify value of polarization-maintaining optical fiber cutoff wavelength.
