When light strikes the photodiode’s active region, current flows from cathode to anode. Ideally, this entire photocurrent ...

One promising solution is the avalanche photodetector, which converts relatively weak optical signals into robust electrical pulses. In such a device, an incoming light pulse strikes a semiconductor, ...

Ultracompact Photodetector Date: August 2, 2016 Source: Karlsruhe Institute of Technology Summary: Data traffic is growing worldwide. Glass-fiber cables transmit information over long distances at ...

The result is a very thin, yet very effective light-absorbing photodetector — a building block for the future of optoelectronics. “It is an enabling technology that allows you to look at a wide ...

The world's thinnest photodetector has been developed. This is a device that converts light into an electric current. With a thickness of just 1.3 nanometers - 10 times smaller than the current ...

Researchers at IBM have made the first photodetector from graphene – a sheet of carbon just one atom thick. The device, which can accurately detect optical data streams at speeds of 10 Gbit/s, could ...

Researchers have developed a photovoltaic device that has an external quantum efficiency of 132 percent. This impossible-sounding feat was achieved using nanostructured black silicon, and could ...

Zheng's color photodetector consists of an ultra-thin oxide coating atop a thin layer of aluminum that was deposited onto a silicon photodetector using a common technique called electron-beam ...

A team of scientists has doubled the efficiency of a photodetector by incorporating a plasmonic lens that encourages surface plasmons to couple to incident photons. The photodetector demonstrates up ...

RMIT University researchers have developed a photodetector that can detect different shades of light in a prototype device made from nano-thin technology.

Increasing the photodetector efficiency in the 905-940nm range could improve LiDAR performance. InGaAs is a compound semiconductor with much better material characteristics than silicon.
