High‐Efficiency Fiber‐Chip Edge Coupler for Near‐Ultraviolet Integrated Photonics (Adv. Mater. Technol. 15/2024)
Fiber-Chip Edge Couplers In article number 2400196, Xingchen Ji, Yikai Su, and co-workers introduce a high-efficiency edge coupler based on an alumina-on-insulator platform, which consists of a symmetric double-tip taper and a multimode interference (MMI)-based optical combiner. The edge coupler is designed to realize efficient mode matching between the single-mode fiber and chip facet via the symmetric double-tip taper at the initial stage, and then combine the two channels in the taper into a highly confined strip waveguide through the MMI-based combiner.
