speeding up mode-converter TopOpt

作者您好，我根据您拓扑优化模式转换器的示例想要逆向设计一个基于sin平台850nm波段的偏振旋转分束器，目前代码都已经写好也可以跑起来但速度特别慢一直得不到一个可以用来流片的结果，想问问您的建议，附件我已经上传，谢谢！

Google translation: Hello author, I'm trying to reverse engineer your example of a topology-optimized mode converter to design a polarization rotating beam splitter based on the sine platform in the 850nm band. The code is already written and runs, but it's extremely slow and I haven't been able to get a usable output for tape-out. I'd like to ask for your suggestions. I've uploaded the attachments. Thank you!
