摘要： 为解决分布反馈光纤激光传感阵列功率一致性的问题,建立了分布反馈光纤激光波分复用阵列输出功率预测模型,采用差值寻优法对激光器进行排序,并通过在阵列尾部增加980nm反射镜进一步提高了阵列的功率均衡水平,实现了阵列结构优化。实验结果表明,优化后的阵列功率波动水平明显改善,有效地解决了阵列末端信号解调效果差的问题,扩大了阵列实际复用容量,提高了组阵效率。上述方法对大规模分布反馈光纤激光器传感器阵列的结构设计具有借鉴价值。

Abstract: To solve the problem of power consistency of distributed feedback fiber laser (DFB FL) sensor array, an output power prediction model of the DFB FL WDM array is established. In the considered model, the laser is ranked by the method of difference optimization, and the power balance level of the array is further improved by adding a 980nm reflector at the end of the array to achieve the structure optimization of the DFB FL sensor array. The experimental results show that the power fluctuation level of the optimized array is significantly improved, and the problem of poor signal demodulation at the end of the array is solved, while the actual multiplexing capacity and the efficiency of the array are improved. The method is of value for the structural design of large-scale DFB FL sensor arrays.

Key words: distributed feedback, fiber laser, structure optimization, power balance, difference optimization
