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 ...

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

In researching my latest article I ran across this paper about a “robust” photodiode amplifier (pdf). I use the scare quotes on purpose, since the whole article seemed a little fishy to me. The author ...

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 ...

Most of us have Ethernet in our homes today. The real backbones of the Internet though, use no wires at all. Optical fibers carry pulses of light across the land, under the sea, and if you’re lucky, ...

Researchers have developed a chip-based quantum random number generator that provides high-speed, high-quality operation on a ...

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