Abstract

A new approach to determining the sensitivity of refractive index sensors is proposed. It has been shown that relative and absolute sensitivity show different results, and also, for the first time, it is demonstrated that relative sensitivity has advantages over absolute sensitivity. In addition, the influence of the relative width of the photonic band gap and the difference in the refractive indices of the layers on the sensitivity are examined and the corresponding dependences of these parameters are obtained. We propose these parameters as a convenient tool for optimizing the sensitivity of sensors based on defective photonic crystals. Finally, results are obtained regarding the behavior of the defect mode at the center of the photonic band gap of one-dimensional photonic crystals.

折射率传感器灵敏度的测定

提出了一种确定折射率传感器灵敏度的新方法。结果表明，相对灵敏度和绝对灵敏度显示出不同的结果，而且首次证明相对灵敏度比绝对灵敏度更具优势。此外，我们还研究了光子带隙的相对宽度和各层折射率的差异对灵敏度的影响，并得出了这些参数的相应依赖关系。我们建议将这些参数作为优化基于缺陷光子晶体的传感器灵敏度的便捷工具。最后，我们还获得了有关一维光子晶体光子带隙中心缺陷模式行为的结果。

期刊介绍： Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
