Organic-compound-based sensors have important applications, such as applications in geothermal power stations, the shoe industry, the extraction of vegetable oil, azeotropic calibration and medical science. Herein, a 1D photonic crystal (PC) with a defect has been used to develop a photonic-technology-based organic compound sensor with optimum performance. The structure of the proposed organic compound sensor consists of a water cavity sandwiched between two symmetric sub-PCs, which are composed of alternate layers of SiO and ZnO. The proposed air/(SiO/ZnO)/cavity/(SiO/ZnO)/glass structure with the optimized structural parameters achieves a quality factor that varies between a minimum value of 4968.2 and a maximum value of 6418.5. The FOM and sensitivity values of the proposed sensing design are on the order of 10 and 10, respectively. The LOD value of the proposed sensor is on the order of 10, which is very low, as is always expected for chemical sensing designs. Thus, the simple design and excellent performance make our design highly efficient and suitable for sensing applications in the industrial and biomedical fields.
基于有机化合物的传感器有重要应用，比如在地热发电站、制鞋业、植物油提取、共沸校准以及医学等方面的应用。在此，一种带有缺陷的一维光子晶体（PC）已被用于开发一种具有最佳性能的基于光子技术的有机化合物传感器。所提出的有机化合物传感器的结构由夹在两个对称子光子晶体之间的水腔组成，这两个对称子光子晶体由SiO和ZnO的交替层构成。所提出的具有优化结构参数的空气/(SiO/ZnO)/腔/(SiO/ZnO)/玻璃结构实现了一个品质因数，其最小值为4968.2，最大值为6418.5。所提出的传感设计的品质因数优值（FOM）和灵敏度值分别约为10和10。所提出的传感器的检测限（LOD）值约为10，这非常低，正如化学传感设计一直所期望的那样。因此，这种简单的设计和优异的性能使我们的设计非常高效，适用于工业和生物医学领域的传感应用。
