Graphene (Gr) has many unique properties including gapless band structure, ultrafast
carrier dynamics, high carrier mobility, and flexibility, making it appealing for ultrafast …

Plasmonic photodetectors are attracting the attention of the photonics community.
Plasmonics is attractive because metallic structures have the ability to confine light by …

Here we propose an original waveguide-integrated plasmonic Schottky photodetector that
takes full advantage of a thin metal stripe embedded entirely into a semiconductor. The …

Silicon photonics for synergistic electronic–photonic integration has achieved remarkable
progress in the past two decades. Active photonic devices, including lasers, modulators, and …

Here, an engineered tunneling layer enhanced photocurrent multiplication through the
impact ionization effect was proposed and experimentally demonstrated on the …

Many consumer technologies rely on photodetection of infrared light, such as lidar, low
visibility imaging, proximity sensors/range finders, etc. However, silicon, the standard …

Photodetectors (PDs) used in communication systems require ultrafast response, high
efficiency, and low noise. PDs with such characteristics are increasingly in demand for data …

In this study, we present an integrated graphene-based photodetector designed for
operation around 1550 nm. Our design features a composite waveguide structure consisting …

Here, we demonstrate the successful application of graphene quantum dots (GQDs) as a
sensitizing material in a self-powered photoelectrochemical (PEC) UV photodetector (PD) …

Sub-bandgap photodetection with two-dimensional electron-confinement in CdZnO-MgZnO
heterojunction is realized. The reported photodetection is based on metal-less internal …
