摘要
为了更准确地研究温度对光纤Lyot型消偏器消偏性能的影响,根据参考文献中光纤消偏器的结构参量,使用保偏光纤熔接机等制作完成了光纤Lyot消偏器,在全温条件(-40℃~80℃)下,其偏振度P≤0.5%;同时搭建了恒温和变温条件下消偏器输出偏振度测试系统,并分析了偏振度改变产生的原因。结果表明,温度恒定在不同值时(-40℃和80℃),消偏器的输出偏振度基本保持不变;当温度按一定梯度升高或者降低时,消偏器的输出偏振度会随之改变。这对于光纤传感应用的研究具有一定的参考价值。
Abstract
In order to study the influence of temperature on the depolarization performance of optical fiber Lyot depolarizers accurately, based on the structural parameters of fiber depolarizers provided in previous references, an optical fiber Lyot depolarizer was made with a polarization maintaining fiber welding machine and its degree of polarization (DOP)P≤0.5% under the total temperature conditions(-40℃~80℃). The test system of the output DOP of the depolarizer under constant and variable temperature conditions was built. The causes of the change of DOP were analyzed. The measurement results show that the output DOP of the depolarizer remains unchanged basically when the temperature is constant at -40℃ and 80℃.The output DOP will change when the temperature changes at a certain gradient. The study has a certain reference value for the research in optical fiber sensing application.
