Researchers have developed the world's first photodetector that can see all shades of light, in a prototype device that radically shrinks one of the most fundamental elements of modern technology.

A multilayered semiconductor acting as an optical sensor opens the way to miniaturized, adjunct spectrometers.

Using graphene, one of science's most versatile materials, engineers have invented a new type of photodetector that can work with more types of light than its current state-of-the-art counterparts.

High-speed photodetectors are vital components in modern optoelectronic systems, especially in enabling ultrafast data transmission and next-generation integrated circuits. The characterisation of ...
