We propose a new optical biosensor based on a photonic crystal with a defectlayer, which can determine the SARS-CoV-2 concentration in water by the defectmode shift. Two models of the dependence of the refractive index of the defectlayer on the concentration of the pathogen in water were considered. Theoptimal parameters for the photonic crystal in our device and the optimalthickness of the defect layer were determined. It was also demonstrated that inthe presence of absorption in the investigated structure it is much moreadvantageous to work in the reflection mode compared to the transmission mode.Finally, the wavelength dependence of the defect mode on the SARS-CoV-2concentration was obtained and the sensitivity of the sensor was determined.
