Abstract
In the proposed work we designed and analysed a two-dimensional photonic crystal based sensor for three different biosensing applications, including measuring the normal and abnormal levels of uric acid, glucose, and creatinine in the blood. We examine the sensitivity, Q factor, and wavelength shift of two different types of sensor cavity design. The simulation approach used a finite difference time domain method. The work has made use of electromagnetic equation propagation, MEEP tool from the Massachusetts Institute of Technology. The maximum sensitivity of the proposed sensor is 282 nm/RIU and Q factor of 5432 was obtained for the structure 1 photonic cavity. Using the IPKISS software framework, a mask design that can be used in the fabrication of a PhC sensor was developed.
