For example, by adding or dropping a particular color, or wavelength, of light traveling in an optical fiber, scientists can control the amount of information carried by the fiber. By altering the ...

To overcome the lack of wavelength-selective extraction in existing on-chip metasurfaces, Chinese scientists developed a novel approach by leveraging a nonlocal on-chip design based on symmetry-broken ...

LEDs offer a new palette of colors to the world of lighting. First, learn these two basic types: soft white and daylight. Soft white refers to warm golden light at 2700 Kelvin, close to the look of ...

Changes in the color and intensity of light pollution over the past few decades result in complex and unpredictable effects on animal vision, new research shows. Changes in the colour and intensity of ...

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 ...
