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 ...

Photodiode and reverse bias supply in series ... For applications that don’t require high-speed photoconductive (photoamperic 3) operation, the switch disables the bias supply and shorts to ...

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 ...

For LiDAR, the team's low-noise, two-micrometer avalanche photodiode enables higher-power operation that is eye-safe. Electrical and computer engineers at the University of Virginia and University ...

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 ...

(Courtesy: Ben Wright, Georgia Tech) Stretchable electronics are engineered with soft mechanical properties to enable conformal operation on complex biological ... use of this e-BHJ in stretchable ...

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 ...

Researchers at Aalto University have developed an infrared photodiode that is 35 % more responsive at 1.55 µm, a key wavelength for telecommunications, compared to other germanium-based components.
