 Abstract black phosphorus, BP, is a unique material with anisotropic optical properties and a direct band gap between 0.3 and 2.0 EV. It has been extensively studied for use in photo detectors, but its performance is limited due to low optical absorption at room temperature. A plasmonic metasurface was designed to match the band edge of BP and to enhance light confinement near the edge of an O-disk. The plasmonic metasurface also enabled a significant quenching of the BP photoluminescence, which was attributed to dipole-dipole coupling. A BP flake was then integrated onto the plasmonic metasurface, resulting in a high-performance mirror photo detector with a peak responsivity of 495.85 mA per W and ultra-high operation speed, greater than 10 MHz. This demonstration opens up opportunities for optoelectronic applications in the mere region. This article was authored by Shom Narayan Singyadov, Palyang Chen, Chonghua Lu, and others.
