An optical filter based on the ring resonator waveguide is proposed. In this study, a Gaussian pulse is used as the optical input signal propagates into a double ring resonator system. The simulation results have shown the filtering signal outputs that can be obtained by using the proposed system. Where the filtering characteristics can be controlled by using the specify parameters, such as the rings radii and the coupling coefficient, of the proposed system. The potential of using such a double ring resonator device for optical communication application is performed and discussed.
