Analogy of Ring Resonators:Single and Double

Ring resonators are one of the crucial required components in the field of channel drop filters. In the proposed curving edge ring resonator with triple layer has been used for ADF. Two types of ADF have been designed with the help of a basic optical based ring resonator. One of them is a single resonator ADF and other one is double resonator ADF. Both filters consist of silicon rods which are suspended in air. The single ADF resonator has add wavelength of 1554nm and drop wavelength of 1585nm with add and drop efficiency of 90% and 68% respectively while the double ring resonator ADF at same add wavelength and drop wavelength has add and drop efficiency of 100% and 91% respectively. The Opti-FDTD software has been used for the simulation work and the comparison table is also drawn between two filters.
