The work is described in an article published on 1st Jan 2025 in the journal Light: Science & Applications. “It took us eight years from the idea to proof-of-concept,” said Prof. Hele Savin. “The ...

In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to ...

Abstract: Multiplication by impact ionization is a very welcome mechanism in photodetectors. Avalanche multiplication by impact ionization is the gain mechanism used for amplification of the ...

That means there would be major benefits from improving the efficiency of infrared sensors, such as photodiodes. Researchers at Aalto University have developed a new type of infrared photodiode ...

New photodiode boosts infrared sensor efficiency Infrared technology sees 35% better responsivity Germanium-based sensor more cost-effective and efficient ...

It includes a 3-channel photodiode mounted in a single package, and is sensitive to blue (λ=390 to 530 nm), green (λ=470 to 600 nm), and red (λ=590 to 680 nm) light. The photosensitive area includes ...

For the last eight years, a team of researchers at Aalto University in Finland has been working to improve the efficiency of photodiodes, a type of infrared sensor that converts light into ...
