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 ...

The newly developed waveguide photodiode can be incorporated into various types of programmable photonic devices to measure the intensity of light travelling in the waveguide, with accuracy ...

Photodetectors are widely used optical components that record the intensity of incident light by converting it into an electrical signal. In the detection process, any information about the phase ...

Spectrally selective light detection is vital for full-colour and near-infrared (NIR) imaging and machine vision. This is not possible with traditional broadband-absorbing inorganic semiconductors ...
