A Cost-Effective Edge Coupler With High Polarization Selectivity for Thin Film Lithium Niobate Modulators

Thin film lithium niobate on insulator (LNOI), as an emerging photonic material, provides a promising platform to realize compact, high-speed, and high-efficient electro-optic (EO) modulators. However, due to the large coupling loss caused by the large mode field mismatch between standard single mod...
