Inverse-Designed Lithium Niobate Waveguide Crossing with Broadband Operation, Low Loss, and Compact Footprint

Waveguide crossings are fundamental building blocks of high-density photonic integrated circuits and on-chip optical routing systems. However, realizing a high-performance, compact waveguide crossing on a lithium niobate-on-insulator (LNOI) platform remains challenging because co...
