锥形弯曲波导的脚本

  这是一个偏振分束器的设计部分图，如图中所示，上波导和下波导均为锥形弯曲波导，上波导的宽度从720nm减小到500nm，下波导宽度由380nm增加到620nm。我尝试用addpoly和addwaveguide写它结构的脚本，一开始在addpoly里加入for循环来完成锥形，虽运行出来了，但是中间的结构是错误的，这个困难我暂时无法自己解决，麻烦老师可以指导一下，这种结构的脚本应该怎么写，谢谢！

  使用Polygon应该可以实现，前提是，每一点的坐标位置计算正确。你再检查一下你的脚本，自己先用手画或者借助第三方软件画一下看看。
  有了弯曲半径，弯曲中心有没有定下来？如果没有定下来的话，不同人画的结果就不同。也可能你需要对这些参数及其范围做进一步了解和分析。
