To generate resonance in the ultraviolet (UV) wavelength region, we have developed a Bragg mirror structure with a SiO2 top layer. This paper shows the wavelength at which sensitivity occurs by modifying the architecture of the one-dimensional photonic crystal (1D-PhC) structure appropriately. The structural parameters are adjusted to excite a Bloch surface wave with a wavelength of 256 and 281 nm at the top interface, which are the operational wavelengths. The spectrum’s distribution of electric fields and mode confinement confirmed the suggested structure with an 8-nm thick defect layer. The proposed design is empathetic at UV wavelength with varying analyte’s refractive index value. The investigation shows that the sensitivity is about 107.42 and 101.85 deg/RIU, and the quality factor is 1426.17 and 1708.14 nm at UV wavelengths of 281 and 256 nm, respectively.

使用紫外线范围评估基于布洛赫表面波的一维光子晶体传感器

为了在紫外 (UV) 波长区域产生共振，我们开发了一种带有 SiO2 顶层的布拉格反射镜结构。本文通过适当修改一维光子晶体 (1D-PhC) 结构的结构来显示发生灵敏度的波长。调整结构参数，在顶部界面激发波长为 256 和 281 nm 的 Bloch 表面波，这是工作波长。电场和模式限制的光谱分布证实了所建议的具有 8 纳米厚缺陷层的结构。所提出的设计在具有不同分析物折射率值的 UV 波长下具有同理心。调查显示，灵敏度约为107.42和101.85 deg/RIU，品质因数分别为1426.17和1708。
