LiDAR sensors are used in professional and scientific settings all the time, but why have them on a smartphone? Turns out, ...

The research team led by Professor Hele Savin has developed a new light detector that can capture more than 96 percent of the photons covering visible, ultraviolet and infrared wavelengths.

Terahertz waves are a form of electromagnetic wave, like gamma-rays, X-rays, ultraviolet light, visible light, infrared light and radio waves (Fig. 1). On the frequency spectrum, terahertz waves ...

Researchers have developed the world's smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human ...

The detector can register incident light in just 40 picoseconds. “In contrast to other semiconductors like silicon or gallium arsenide, graphene can pick up light with a very large range of photon ...

The team has filed a patent application for the new light detector. The prototype detectors are currently being tested in imaging applications related to medicine and safety.

Indeed, the nanostructure used in the new light detector is similar to that used by the team a couple of years ago in their record-high efficiency black silicon solar cells. The team filed a patent ...

Autonomous vehicles could be given extra awareness thanks to a unique light detecting device that can more accurately amplify weak signals reflected from faraway objects. Developed by engineers at the ...
