Abstract

Abstract. 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.
紫外波段布洛赫表面波一维光子晶体传感器的评价
摘要为了在紫外线(UV)波长区域产生共振,我们开发了一种具有SiO2顶层的布拉格反射镜结构。本文通过适当地修改一维光子晶体(1D PhC)结构的结构,展示了灵敏度发生的波长。调整结构参数以在顶部界面处激发波长为256和281nm的布洛赫表面波,这是操作波长。电场的光谱分布和模式限制证实了所提出的具有8nm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紫外线波长下是移情的。研究表明,在281和256nm的紫外波长下,灵敏度分别为107.42和101.85deg/RIU,品质因数分别为1426.17和1708.14nm。
