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 ...

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 ...

Engineers at Stanford have created a new optical device that can easily manipulate light into basically any color desired. The system uses a series of modulators to fine-tune the frequencies of ...

A week or so ago, I got a question on Facebook that was relayed from one of the kids of a college friend, which I'll paraphrase as "What's the physics explanation of what gives objects their color?" ...

Beyond light, noise also possesses a spectrum of colors, each with a unique frequency profile. These 'colors of noise,' like ...
