Abstract— Photonic crystal biosensors is a new, advance and accurate measurement technology for bio sensing application. In this paper, a two dimensional (2D) photonic crystal nanocavity and microcavity sensor is designed for the detection of dengue using human blood plasma and platelets. The optical properties of plasma and platelets are observed and refractive index of normal plasma, infected plasma, normal platelets and infected platelets are used. The change in output transmission spectrum and Q factor has been observed with the shift in wavelength, thus by observing these changes dengue is detected. The designed sensor can predict results accurately and in short time, hence can be used for medical application. By designing micro and Nano cavity in same structure of biosensor, comparison is also done and results of Q factor and transmission are also observed. The band gap range of structure is 1360 nm to 2190 nm and 1550 nm continuous modulated wave is used in this design. The finite difference time domain (FDTD) method is used to analyze the result and Plane wave expansion (PWE) method is being used for band gap calculation.
