由于工艺限制,刻蚀的直波导和圆环波导都是有一定的侧壁角的,侧壁角在直波导中仿真问题可以用waveguide来解决,那Ring的话如何仿真会更准确呢?
1)用三阶贝塞尔函数来仿真,虽然可以做到侧壁角,但与ring相比相差有点大
2)用矩形近似,但要仿真多波长光源输入,仍会造成不准确。
感谢解答!

目前侧壁角生成方法一般用Planarsolid https://optics.ansys.com/hc/en-us/articles/360034382334-Tips-for-adding-sidewall-angles-to-simulation-objects
你试一下看看增加点数能否改善。
另一种方法就是用很多不同半径的圆环一层一层垒起来,你看看结构组中类似的例子。
