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 ...

Quantum materials just made light do the "impossible", unlocking hidden terahertz waves that could transform future technology.

Aquatic algae called diatoms have been found to use light-sensing proteins as depth indicators. Detecting depth-related changes in the intensity and spectrum of light enables algae to modulate their ...

A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction grating to break ...
