Abstract

Fiber-chip edge couplers are extensively used in integrated silicon photonic for the coupling of light between optical fibers and planar silicon waveguide circuits. We experimentally demonstrate several novel designs of edge couplers with eased fabrication process, i.e. fork shape and dual-trident SWG shape, based on Silicon-on-Insulator platform. These edge couplers show low coupling losses and possess large bandwidths simultaneously.
