Design and Simulation of High Efficient Bident Edge Coupler Based on Thin-Film Lithium Niobate
High coupling efficiency (CE) edge coupler are crucial for thin-film lithium niobate (TFLN) photonic integrated devices. We design and simulate a kind of high-performance b ident edge coupler based on TFLN using genetic algorithm. The results show that the coupler has a CE of about 0.61 dB (1550 nm). The results also show that the designed structure has a favorable tolerance to fiber alignment errors in the z direction.
