Abstract. Due to the dire need to monitor, sense, and control useful and harmful chemicals for industrial, environmental, and biomedical purposes, chemical sensing has become an eminent topic among researchers. Hence, we focus mainly on a modified kagome design with a relatively high sensitivity of 99.8%, effective material loss of 0.000263 cm − 1 for constant absorption loss, and 0.0004204 cm − 1 for variable absorption loss and low confinement loss of 2.117 × 10 − 17 cm − 1 investigated with the help of the full vector finite element method in Comsol multiphysics using water, ethanol, and benzene as analytes while considering other parameters, such as nonlinearity, dispersion, numerical aperture, and effective area which are equally investigated and discussed. The results obtained are tabulated and compared with recent works published.

一种用于化学传感的高灵敏八边形空芯光子晶体光纤的设计与分析

摘要。由于迫切需要监测、感知和控制用于工业、环境和生物医学目的的有用和有害的化学物质,化学传感已成为研究人员的一个突出话题。因此,我们主要关注具有 99.8% 相对高灵敏度、0.000263 cm - 1 的恒定吸收损耗和 0.0004204 cm - 1 的可变吸收损耗和 2.117 × 10 - 低限制损耗的改进 kagome 设计。 17 cm - 1 借助 Comsol multiphysics 中的全矢量有限元方法进行研究,使用水、乙醇和苯作为分析物,同时考虑其他参数,例如非线性、色散、数值孔径和有效面积,这些参数也进行了同等研究和讨论. 将获得的结果制成表格并与最近发表的作品进行比较。
