Editor’s note: This article will be in two parts. Part 1 is component-related and Part 2 is applications. Please also see Planet Analog blog “LEDs Are Photodiodes Too” as an intro to this article.

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 ...

So what limits the speed of a photodiode? Consider the operation of a conventional p–i–n photodiode that consists of a sandwich of thin p-doped, intrinsic (i) and n-doped layers of semiconductors.

What many of us may be unaware of though is that an LED is also a photodiode, and can even be persuaded to generate usable quantities of power. [Voltative] takes a look at this phenomenon with a ...

Researchers developed a single photodiode sensor that detects full-color light using ... introduce other trade-offs, such as slower operation and higher instability. At the core of this limitation is ...

"We are developing the technology of micropixel photodiodes based on printed principles. The new study shows an important result — the effective operation of photodiodes for X-ray conversion has been ...

In this study, the optimized 0.5 micrometer thick thin-film photodiode demonstrated a sensitivity of 1.8×1012 Jones, similar to a silicon photodiode.In addition, it was stably operated for more ...

What is a PIN avalanche photodiode (APD)? What is a PIN photodiode? How to characterize avalanche breakdown in GaN. Major differences exist between a PIN photodiode and an avalanche photodiode ...

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

Trumpf’s new VCSEL laser diodes and photodiodes supporting up to 56Gbps. Trumpf Photonic Components is to showcase new VCSELs (Vertical Cavity Surface Emitting Lasers) and photodiodes for applications ...
