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 ...

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 ...

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 ...

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?" ...

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 ...
