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.

Optical pulses, which appear as a flash of light, are used to transmit information in high speed optical fibers, and are increasingly used in Light Detection And Ranging (LIDAR) for 3-dimensional ...

Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to self-driving cars and virtual reality headsets. That means there would be major ...

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 ...

Integrating a dual photodiode, LED drive circuitry, and a signal processing circuit in a subminiature plastic package, the S8030 and S8064 photo ICs are designed to accurately determine the proximity ...

New TOPLED® D5140, SFH 2202 photodiode provides higher sensitivity and much higher linearity than standard photodiodes on the market today Wearable devices using the TOPLED® D5140, SFH 2202 will be ...

Phlux Technology has announced 1550nm avalanche photodiode with a 3.5GHz cut-off. Part of its existing Aura range, the speed increase comes from a reduced die size, down to 30µm from 80µm (1.8GHz) or ...

In this section we shall discuss the interface between a photosensor and its associated electronics. There are really just two photocell applications – light measurement, and the reception of ...
