How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

A tiny metasurface chip can turn invisible infrared light into steerable visible beams, opening the door to powerful new ...

An international research team demonstrates how to generate extremely short pulses of visible light using an industrial-grade laser system. Visible light is extremely important in nature. Seen by the ...

Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials. Lenses ...

A study participant puts in a contact lens. Researchers developed lenses with nanoparticles that convert infrared wavelengths into visible light that humans can perceive. Yuqian Ma, Yunuo Chen, Hang ...

Can we use nothing more than sunlight and inexpensive materials to produce clean hydrogen fuel while also removing toxic pollutants from water? That question shaped our recent work with γ-In2S3, a ...
