Abstract

The following work represents a propagation and power flow investigation for different organic liquids of an optical channel drop filter on a 2D photonic crystal flower ring resonator. The structure is composed of dielectric rods immersed in air and based on photonic crystal ring resonator. The ring resonator is formed as a flower shape and is sandwiched by two wave guides. For analyzing this structure, plane –wave expansion (PWE) approach and finite element method is applied. The numerical results shows the propagation and the power flow variations for different organic liquids used. This variation is due to their refractive index which varies from one material to another. In this work, we fixed the radius ‘r’ and the lattice constant ‘a’ by interesting to the refractive index which is an important parameters of each materials used.
