A double-clad single-mode tellurite optical fiber (DC-SMTOF) with a loss of 0.5 dB/m @1545.1 nm was fabricated based on the TeO2–ZnO–Li2O–Bi2O3 (TZLB) material. During the fiber drawing process, a low level of residual birefringence was produced, which gave a chance for the investigation of the polarization modulation instability (PMI). With a nanosecond laser operated at 1545.1 nm as the pump source, the PMI effect in the DC-SMTOF was investigated using different fiber length and different average pump power. This investigation of the PMI generation in non-silica optical fibers may provide guidance for the generation of the highly repetitive optical pulse train.

双包层单模碲酸盐光纤偏振调制不稳定性的实验研究

基于 TeO2–ZnO–Li2O–Bi2O3 (TZLB) 材料制造了一种双包层单模碲酸盐光纤 (DC-SMTOF),其损耗为 0.5 dB/m @1545.1 nm。在光纤拉制过程中,产生了低水平的残余双折射,这为研究偏振调制不稳定性 (PMI) 提供了机会。以工作在 1545.1 nm 的纳秒激光器作为泵浦源,使用不同的光纤长度和不同的平均泵浦功率研究了 DC-SMTOF 中的 PMI 效应。这项对非二氧化硅光纤中 PMI 生成的研究可以为高度重复的光脉冲序列的生成提供指导。
