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 ...

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 ...

How do you find the quality of the light a light bulb produces? Using the color rendering index, a measure of how well a light bulb illuminates a range of colors. Appliance Science looks at the ...

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 ...
