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

In this paper, we proposed an all optical 4-to-2 encoder that has 4 input and 3 output ports. This device generates a 2 bit binary code based on which input port is active. We used nonlinear photonic crystal ring resonators along with optical power splitter for realizing the proposed encoder. In this device the switching rate and area are obtained about 333 GHz and 612µm2 respectively.
