In this work, we obtained chirped Bragg gratings by post-coating uniform poly (methylmethacrylate) (PMMA) microstructured polymer optical fiber Bragg gratings (POFBGs) with an UV cure adhesive. The main advantage of the proposed method consists on being a cost-effective and simple solution, since no special phase mask, additional etching or gradient thermal annealing are required. A comparison between the fabricated chirped Bragg grating’s performance and previous reported methods in the literature is presented. As a compact sensor with two different active areas (adhesive coated and uncoated sections of the POFBG), the developed sensing device can be used for multiparameter sensing, namely for strain, humidity and temperature monitoring. Allying the proposed flexible and low-cost fabrication technique with the intrinsic characteristics of POFs, one may conclude that the developed sensor has high potential for multiparameter sensing in possible future engineering and biomedical applications.

在这项工作中，我们通过用紫外线固化粘合剂后涂均匀的聚甲基丙烯酸甲酯 (PMMA) 微结构聚合物光纤布拉格光栅 (POFBG) 来获得啁啾布拉格光栅。所提出方法的主要优点在于它是一种经济高效且简单的解决方案，因为不需要特殊的相位掩模、额外的蚀刻或梯度热退火。介绍了制造的啁啾布拉格光栅的性能与文献中先前报道的方法之间的比较。作为具有两个不同活性区域（POFBG 的粘合剂涂层和未涂层​​部分）的紧凑型传感器，开发的传感设备可用于多参数传感，即应变、湿度和温度监测。将所提出的灵活且低成本的制造技术与 POF 的固有特性相结合，
