Hamamatsu Photonics is pleased to announce the launch of its latest indium gallium arsenide (InGaAs) photodiodes (PD) series designed for longer wavelengths. The G1719X series are near-infrared ...

Critical infrastructure is a key target of both physical and cyberattacks. Microsoft has observed an increase in reported attacks on internet-exposed operational technology (OT) devices that control ...

Abstract: This paper explores the inter-subband scattering properties in n-p-n quantum well heterojunction bipolar light-emitting transistors (QW-HBLETs or LETs). We showed a steady-state method to ...

Passively-cooled SPADs could be realized by avalanche materials exhibiting better temperature stability. A promising candidate is the InGaAs/AlGaAsSb SPAD, because the AlGaAsSb multiplier is highly ...
