Optoelectronics hold a range of possibilities for the hardware experimenter — indeed who among us hasn’t added LEDs aplenty to our work? What many of us may be unaware of though is that an LED is also ...

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 photonics research. Unlike conventional electronics that transmit signals with ...

Une photodiode est un composant semi-conducteur ayant la capacité de détecter un rayonnement du domaine optique et de le transformer en signal électrique. Pour avoir une meilleure efficacité quantique ...

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

Photodiode is a type of light detector capable of converting light energy into either current or voltage, depending upon the mode of operation. Photodiodes are similar to typical semiconductor diodes ...

This week, at the IEEE International Electron Devices Meeting (IEDM 2025), imec, a research and innovation hub in advanced ...

Electrical and computer engineers have developed an avalanche photodiode that achieved record performance and has the potential to transform next generation night-vision imaging and Light Detection ...

Marktech had revealed the latest in its line of sensors which combine many LEDs of different wavelengths with a photodiode. MTMD142345PDT38 has five LEDs at 1.04, 1.2, 1.3, 1.46 and 1.55μm, plus an ...

Imec, the Leuven, Belgium-based research and innovation hub in nano- and digital technologies, has announced the successful integration of a “pinned photodiode structure” in thin-film image sensors.

This Photodiode based Alarm can be used to give a warning alarm when someone passes through a protected area. The circuit is kept standby through a laser beam or IR beam focused on to the Photodiode.
