论文摘要
我们提出了基于具有缺陷层（DL）的光子晶体（PC）的光学生物传感器的改进结构，该光子晶体（PC）可以通过缺陷模式（DM）移位检测水中SARS-COV-2的浓度。我们研究了4种有缺陷的PC，其中包括完美PC内部不同的图层布置及其对传感器性能的影响。 DM的灵敏度和振幅是DL厚度的函数。同样，研究了在DL存在下边缘模式的特殊性。最后，我们获得了一个特征方程，以确定内部具有各向同性缺陷的任意1D PC的DMS波长。
We propose an improved structure of an optical biosensor based on a photonic crystal (PC) with a defect layer (DL), which can detect the concentration of SARS-CoV-2 in water by defect mode (DM) shift. We investigated 4 types of defective PCs with different arrangements of layers inside the perfect PCs and their impact on the performance of the sensor. The sensitivity and amplitude of DM were examined as a function of DL thickness. Also, the peculiarities of edge modes in the presence of DL were investigated. Finally, we obtained a characteristic equation to determine the wavelengths of DMs for an arbitrary 1D PC with an isotropic defect inside.
