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 ...

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.

Single-photon detectors (SPDs) are the most sensitive instruments for light detection. In the near-infrared range, SPDs based on III–V compound semiconductor avalanche photodiodes have been ...

Researchers at the University of Bristol have made an important breakthrough in scaling quantum technology by integrating the world’s tiniest quantum light detector onto a silicon chip.
