Abstract

We investigate the properties of ring resonators that are supported by a two-dimensional photonic crystal waveguide. The proposed structure composed of a photonic crystal ring resonator (PCRR) with four scatters can really function as a wavelength division multiplexer. The significance of the design is that the output waveguide is perpendicular to the ring resonator. We numerically demonstrate that the proposed four-channel PCRR device with 3 × 3 inner dielectric rods can provide a transmission efficiency larger than 92%, a quality factor higher than 3800, and crosstalk of less than 32 dB .
