Abstract

In this paper a two dimensional photonic crystal based super structure which can sense different bio-analytes in blood for biomedical applications has been successfully demonstrated with a very high quality factor. Simulation and analysis has been done for Cytop (polymer), Blood Plasma, Ethanol, Hemoglobin, Glucose solution (40gm/100ml), Biotin-Streptavidin and Bovine Serum Albumin. Finite Difference Time Domain (FDTD) method has been used for the analysis. MEEP (MIT Electromagnetic Equation Propagation) simulation tool has been used for modeling and designing of photonic crystal super structure. The optical properties of different bio-analytes are studied and the normalized power and Q factor has been observed for bio- analytes which can be used for blood analysis. It has been observed that for little change in dielectric constant (∈) there will be a moderate shift in the transmitted output power and quality factor and hence it acts as a sensor. This indicates that it is highly sensitive for the change in refractive index.
