Abstract:A 2D photonic crystal based biosensor using rhombic ring resonator is proposed and designed for monitoring the concentrations of glucose. The optical characteristics of rhombic ring resonator is analyzed and predicted by Finite Difference Time Domain method. A new structure of rhombic ring resonator is formed by utilizing bi-periodicity in the design of 2D silicon PC slab in hexagonal lattice with the size of 10 µm and 12µm in X and Z direction, respectively. The sensing parameters are observed in the rhombic … Show more
