摘要
En 中文
We propose and demonstrate a three-dimensional nano-printed four-channel vertical coupler array on the silicon-on-insulator plat form for efficient chip-to-multicore fiber coupling. The proposed structure provides less than 1 dB loss in a single lane and around 2-4 dB loss in multicore fiber coupling, over 100 nm 1 dB bandwidth, and large 1 dB misalignment tolerances of more than 5 AM in the x y plane and 20 mu m in the z direction. The device shows great promise for photonic integrated devices for space-division-multiplexing technology based on multicore fiber. (C) 2021 Optical Society of America
