Electrical and computer engineers at the University of Virginia and University of Texas-Austin have developed an avalanche photodiode that achieved record performance and has the potential to ...

A research team has increased the stability and performance of photodiodes using cubic perovskite nanocrystals. The result expected to be used for autonomous vehicles, military, space exploration and ...

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

A photodiode also referred to as a photo-detector is a semiconductor device that converts light energy into an electrical current. Photodiodes are sensitive to light across a specific range of ...

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 ...

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 ...

For fitness devices, Osram has combined three different colour LEDs and a photodiode in a single 4.7×2.5×0.9mm package for reflective blood oxygen and pulse sensing. Leds in the SFH 7050 are 530nm ...

In researching my latest article I ran across this paper about a “robust” photodiode amplifier (pdf). I use the scare quotes on purpose, since the whole article seemed a little fishy to me. The author ...
