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 ...

Hamamatsu Photonics, a provider of photonic sensors, announces the launch of the S16495 silicon photodiode. Engineered for ...

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 ...

APD28A, 25G Avalanche Photodiode, offers high bandwidth, high sensitivity and wide wavelength operation range for 25G NRZ and 50G PAM-4 applications MAOD-131F25, directly modulated 25G 1310nm ...

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.

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 ...

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.

Silicon-based photodiodes are widely used due to their low cost, low noise, and compatibility with standard IC technologies. However, silicon has a bandgap of 1.12 eV—equivalent to a wavelength of ...

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 ...

When the topic is radiation detection, thoughts turn naturally to the venerable Geiger-Müller tube. It’s been around for ages, Russian surplus tubes are available for next to nothing, and it’s easy to ...

Patent-pending technology has been tapped to develop a two-dimensional silicon (Si) photodiode array that exhibits extremely low crosstalk. Manufactured using a micro-machining process, the S8593 is a ...
