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.
