Popis: Silicon photonic devices have great potential for photocommunication, and silicon-based photodetectors have attracted wide attention. Here, we report an on-chip integrated microfiber–silicon–graphene hybrid structure photodetector that can operate in the visible and near-infrared ranges. The detector has a responsivity of ∼136 mA W−1 at 808 nm and a rise time of ∼1.1 μs. At a reverse bias of 5 V, we achieved a responsivity of ∼1350 mA W−1. Our device provides an option for on-chip integration.
