Abstract :

In this paper, a new design of demultiplexer based on two-dimensional photonic crystal ringresonator is proposed. The structure is made of a hexagonal lattice of silicon rods with therefractive index 3.46 in coefficient of air with refractive index 1. The transmission efficiencyand Quality factor for our proposed demultiplexer, respectively, are more than 65% and1600. The normalized transmission spectra of the photonic crystal ring resonator are takenusing Two-dimensional (2D) Finite Difference Time Domain (FDTD) method. The photonicband gap is calculated by Plane Wave Expansion (PWE) method.
