High-frequency light is useful. The higher the frequency of light, the shorter its wavelength – and the shorter the wavelength, the smaller the objects and details the light can be used to see. So ...
Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor ...
A study demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible light, and that this mechanism is ultrafast and tunable. These outcomes open ...
