Abstract

We propose and evaluate a 2-D photonic crystal waveguide with two line defects separated by a row of elliptic air holes. By adjusting the structural parameters, we obtain a waveguide with an inflection point on the dispersion curve corresponding to a slow-light mode with reduced distortion. Moreover, we investigate the transversely confined field and high quality factor, which both indicate that the dispersionless slow wave can be generated in our wave guide.
