| Abstract: | In order to improve the performance of biochemical sensor,a new type of biochemical sensor based on optical ring resonator is designed.Firstly,the structure parameters of ring resonator are introduced.Then,the optical characteristics of the ring resonator are simulated and the structure of the ring resonator is optimized by FDTD.At the same time,the sensitivity of the resonator to the refractive index is verified.Finally,the structure of the ring resonator biosensor is designed by using L-Edit software,and a simulation model is built.Through simulation optimization and sensitivity verification,the sensitivity of the optimized device is improved.The biochemical sensor constructed by the resonant cavity coupling unit can be used to detect the biological concentration and microbial reaction information in the air and liquid,which is very suitable for the sensor structure design with high requirements for biochemical special rapid detection,and has a wide application prospect. |
