WebJun 29, 2024 · We implement an edge coupler featuring low coupling loss and ultra-broad bandwidth. The off-chip efficiency at 755 and 1550 nm is 3 and 1 dB / facet, respectively. The experimental coupling efficiency of the coupler in the near-visible light band is 3 dB higher than the simulated efficiency of the traditional two-layer structure. WebFiber-chip edge couplers are extensively used in integrated silicon photonic for the coupling of light between optical fibers and planar silicon waveguide circuits. Here, we experimentally demonstrate three kinds of edge couplers with eased fabrication process, two fork shape, and one dual-trident SWG shape, based on Silicon-on-Insulator platform. A …
