发布时间：2018-12-12 02:32
【摘要】：消光比是表征单偏振光纤偏振性能好坏的特征参数之一,影响它的因素有很多,如光谱带宽。结合熊猫型单偏振光纤的测量,搭建了双轴光谱带宽测量系统,通过对单偏振光纤的光谱带宽、消光比参数的大量测量和分析,找到了光谱带宽对消光比参数影响的原因。结论是单偏振光纤的工作波长要远离光谱带宽的下限位置,即HE_(11y)模式的截止损耗峰,另外,要求HE_(11y)模式的截止损耗要陡峭,这样才能保证单偏振光纤具有高消光比特性。
[Abstract]:Extinction ratio is one of the characteristic parameters to characterize the polarization performance of single-polarization fiber. There are many factors affecting it, such as spectral bandwidth. A biaxial spectral bandwidth measurement system is built based on the measurement of panda type single polarization fiber. By measuring and analyzing the spectral bandwidth and extinction ratio parameters of single polarization fiber, the reasons for the influence of spectral bandwidth on extinction ratio parameters are found. The conclusion is that the operating wavelength of single-polarization fiber should be far from the lower limit of spectral bandwidth, that is, the cut-off loss peak of HE_ (11y) mode, in addition, the cut-off loss of HE_ (11y) mode should be steep. Only in this way can the single polarization fiber have high extinction ratio.
