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

By harnessing two natural timescales in resonator arrays, researchers created photonic chips that reliably produce multiple harmonics without active compensation. For decades, scientists and engineers ...

An international team led by researchers at Penn State and Université Paris-Saclay has gained precise control over light emitted from nanoscale sources embedded in two-dimensional (2D) materials. This ...

By carefully choosing the orientation of the crystal, they were able to produce stable microcombs on the chip. In their latest work, they generated a special kind called a normal dispersion Kerr ...

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 ...

How does color work, and how does the type of light source you use affect the colors you see? Appliance Science looks at the science of light and color. Richard Baguley Richard Baguley has been ...

Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest photonic chips go a step further by splitting a single laser into a ...
