As an important chip for receiving optical information in a visible light communication
system, visible light photodetectors (PDs) modulate the bandwidth and responsivity, which …

Infrared photodetectors have been used extensively in biomedicine, surveillance,
communication and astronomy. However, state of the art technology based on III-V and II-VI …

Digital camera sensors use color filters on photodiodes to achieve color selectivity. As the
color filters and photosensitive silicon layers are separate elements, these sensors suffer …

Due to the advantages of narrow energy distribution of plasmonic hot-electrons in Ag and
the high density of states in the TiO2 conduction band, an Ag/TiO2 composite is considered …

Ultrafast lasers play important roles for scientific research and industrial applications.
Saturable absorbers serve as crucial components for ultrafast laser generation. For …

Sub-bandgap near-infrared silicon (Si) photodetectors are key elements in integrated Si
photonics. We demonstrate such a Si photodetector based on a black Si (b-Si)/Ag …

Single wall carbon nanotube (SWCNT)/Si heterojunction photodetectors have the
advantages of high photoresponse ability and simple structure, however, their detection …

Plasmonic sensors have great potential for widespread usage. However, the prohibitive cost
of noble metals restrains the wider adoption of these devices. The aim of our study is to …

In this paper, a novel InP-based evanescently coupled hybrid plasmonic uni-traveling carrier
photodetector (ECHP-UTC-PD) integrated with a hybrid plasmonic waveguide is proposed …

Binary metal layers composed of a grating and a thin film are designed for high-responsivity
metal–insulator–metal (MIM) near-infrared hot-electron photodetectors (HEPDs). The binary …
