We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

哪一侧包含高折射材料导致问题就在那里用其模式做输入。

优化Taper长度可以单独做,就是先用FDTD计算多少模式能注入Taper,然后用一两个主要模式做Taper优化即可。仿真Taper时就不要包含高折射率衬底了,因为它可能仅产生很小的损耗,但是给仿真带来极大可能。可以适当简化器件模型。
