Abstract

We propose an improved structure of an optical biosensor based on a photonic crystal with a defect layer, which can detect the concentration of organic contaminants in water by defect mode shift. We investigated 4 types of defective photonic crystals with different arrangements of layers inside the perfect photonic crystals and their impact on the performance of the sensor. The sensitivity and amplitude of defect mode were examined as a function of defect layer thickness. Also, the peculiarities of edge modes in the presence of defect layer were investigated. Finally, we obtained a characteristic equation to determine the wavelengths of defect modes for an arbitrary 1D photonic crystal with an isotropic defect inside.

基于缺陷层光子晶体的高性能传感器

我们提出了一种基于缺陷层光子晶体的光学生物传感器的改进结构，它可以通过缺陷模移位检测水中有机污染物的浓度。我们研究了完美光子晶体内部不同层位排列的4种缺陷光子晶体及其对传感器性能的影响。研究了缺陷模的灵敏度和幅值与缺陷层厚度的关系。同时，研究了缺陷层存在时边缘模的特性。最后，我们得到了一个特征方程，用于确定内部具有各向同性缺陷的任意一维光子晶体的缺陷模波长。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
