Programmable photonics devices, which use light to perform complex computations, are emerging as a key area in integrated ...

Using a bootstrapping scheme with a JFET can enhance a photodiode’s ac response, but adds unwanted dc voltage. Remedy that problem with a matched dual-JFET. 1. This circuit uses a JFET to bootstrap ...

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 ...

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 ...

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 ...

Direct coupling is advantageous in many photodetector applications, such as viewing laser thresholds and modulation depth. I patented a very fast photodetector mount 1,2 in the early 1970s using these ...

SI Sensors design novel CMOS image sensors for ultra-fast cameras that increase the velocity of the signal electrons allowing them to be swept out of the photodiode and be detected much faster.

Programmable photonics promises faster, more energy-efficient computing than electronics by transmitting signals using light.
