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 a few ...

Programmable photonics devices, which use light to perform complex computations, are emerging as a key area in integrated ...

Designing high-resolution detection circuits using photodiodes presents considerable challenges because bandwidth, gain, and input-referred noise are coupled together. This application note reviews ...

In this section we shall discuss the interface between a photosensor and its associated electronics. There are really just two photocell applications – light measurement, and the reception of ...

Researchers developed a single photodiode sensor that detects full-color light using perovskite materials, impedance data, and machine learning algorithms. (Nanowerk Spotlight) Conventional ...

Powerful, inexpensive and even flexible when they need to be, organic photodiodes are a promising alternative to silicon-based photodetectors. They are used to improve light sensitivity in cameras and ...

Programmable photonics promises faster, more energy-efficient computing than electronics by transmitting signals using light.
