我们提出并评估了一个二维光子晶体波导，其中两个线缺陷被一排椭圆空气孔隔开。通过调整结构参数，我们得到了一个波导的色散曲线上的拐点对应于一个慢光模式与减少失真。此外，我们研究了横向受限场和高品质因子，这都表明，无色散慢波可以在我们的波导中产生。
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.
