Modelling of 2D Photonic Crystal based Micro Ring Resonator Sensor for the Detection of Malaria

Abstract

In this paper, a 2D Photonic crystal based optical biosensor has been proposed and modelled for the detection of malaria. The model comprises of an optical micro ring resonator. The variation in the refractive index (RI) of the human blood cells has been observed from the normal to the infected one. This variation leads to the shift in intensity of the light and helps to detect whether the cell is normal or infected. The proposed design has high sensitivity of 942.8 nm/RIU with a Q-factor of around 750. The simulation and analysis of the design has been done using Finite difference time domain (FDTD) method.
