论文摘要
我们提出了一种基于缺陷层的光子晶体的新光学生物传感器，该光子晶体可以通过缺陷模式移位来确定水中的SARS-COV-2浓度。考虑了缺陷层折射率对水中病原体浓度的依赖性的两个模型。确定了我们设备中光子晶体的最佳参数和缺陷层的最佳厚度。还证明，在研究结构中吸收的情况下，与传输模式相比，在反射模式下工作更具优势。最后，获得缺陷模式对SARS-COV-2浓度的波长依赖性，并确定传感器的灵敏度。
We propose a new optical biosensor based on a photonic crystal with a defect layer, which can determine the SARS-CoV-2 concentration in water by the defect mode shift. Two models of the dependence of the refractive index of the defect layer on the concentration of the pathogen in water were considered. The optimal parameters for the photonic crystal in our device and the optimal thickness of the defect layer were determined. It was also demonstrated that in the presence of absorption in the investigated structure it is much more advantageous to work in the reflection mode compared to the transmission mode. Finally, the wavelength dependence of the defect mode on the SARS-CoV-2 concentration was obtained and the sensitivity of the sensor was determined.
