MXene materials help photodetectors see the light

Photodetectors are the devices that convert information carried by light into an electric signal that can be processed by electronic circuits and computers. They are found in everyday devices, such as television remotes and ...

Quantum sensor for photons

A photodetector converts light into an electrical signal, causing the light to be lost. Researchers led by Tracy Northup at the University of Innsbruck have now built a quantum sensor that can measure light particles non-destructively. ...

Graphene gives a tremendous boost to future terahertz cameras

In a recent study, researchers developed a novel graphene-enabled photodetector that operates at room temperature, is highly sensitive, fast, has a wide dynamic range, and covers a broad range of THz frequencies. The researchers ...

New method improves infrared imaging performance

A new method developed by Northwestern Engineering's Manijeh Razeghi has greatly reduced a type of image distortion caused by the presence of spectral cross-talk between dual-band long-wavelength photodetectors.

Perovskites – materials of the future in optical communication

Researchers at the universities of Linköping and Shenzhen have shown how an inorganic perovskite can be made into a cheap and efficient photodetector that transfers both text and music. "It's a promising material for future ...
