我们表征了全氟化渐变折射率聚合物光纤 (PFGI-POF) 在 1.32 μm 和 1.55 μm 处的布里渊增益光谱 (BGS)。对三种具有相同纤芯直径但由不同制造商制造的 PFGI-POF 进行了测试。对于所有 PFGI-POF，由于传播损耗较低，在 1.32 μm 处测得的斯托克斯功率高于 1.55 μm 处的斯托克斯功率，但三者之间的斯托克斯功率存在显着差异。基于光时域反射计获得的测量结果，我们表明PFGI-POF的实际传播损耗在观测BGS中起着至关重要的作用。
We characterize the Brillouin gain spectra (BGS) in perfluorinated graded-index polymer optical fibers (PFGI-POFs) at 1.32 μm and 1.55 μm. Three kinds of PFGI-POFs with the same core diameter, but which are fabricated by different manufacturers, are tested. For all the PFGI-POFs, the Stokes power measured at 1.32 μm is higher than that at 1.55 μm due to the lower propagation loss, but significant differences in Stokes power are observed among the three. Based on the measurement obtained by the optical time-domain reflectometry, we show that the actual propagation loss of the PFGI-POFs plays a crucial role in observing BGS.
