摘要

提出了一种基于光频域偏振法(OFDP)的保偏器件分布式偏振串扰(DPC)测量方法。针对激光非线性扫频引起的相位误差，提出了一种插值重采样算法。此外，提出了一种迭代色散补偿算法来抑制DUT双折射色散的影响。对500m长度的PM光纤线圈的测量结果与传统光学相干域偏振法(OCDP)的测量结果对比表明，OFDP方法具有>10 dB的动态范围和更短的测量时间。为DPC的动态测量提供了广阔的前景。

Distributed polarization crosstalk measurement based on optical frequency domain polarimetry

A distributed polarization crosstalk (DPC) measurement method for a polarization-maintaining device is proposed based on optical frequency domain polarimetry (OFDP). An interpolation resampling algorithm is presented to correct the phase error induced by the nonlinear frequency sweep of the laser. Furthermore, an iterative dispersion compensation algorithm is proposed to suppress the influence of the birefringence dispersion of the DUT. A comparative measurement result for a 500m-length PM fiber coil between the OFDP and the conventional optical coherence domain polarimetry (OCDP) method demonstrates that the OFDP method has a superior dynamic range of >10 dB and a much less measurement time. It shows promise for the dynamic measurement of DPC.
