摘要：
We present topology optimization enhancements for thin-film lithium niobate, enabling optimization for structures with nonvertical sidewalls and anisotropic media. We validate our enhancements by optimizing and measuring the first topology optimized polarization demultiplexing grating coupler on thin-film lithium niobate.
