A chip-scale broadband light source in silicon carbide

Optical frequency combs have changed science and technology as we know it. Responsible for measuring things like infrared and ultraviolet light, greenhouse gases, atomic clocks, and disease, optical frequency combs act as ...

A remote control for functional materials

Intense mid-infrared excitation has been demonstrated as a powerful tool for controlling the magnetic, ferroelectric and superconducting properties of complex materials. Nonlinear phononics is key to this end, as it displaces ...

An optical chip improved by light

Technology is increasingly moving towards miniaturization and energy efficiency. This also applies to electronic chips. Light, and optics more broadly, are functional in making compact and portable chips. Researchers from ...

An X-ray vision-like camera to rapidly retrieve 3D images

It's not exactly X-ray vision, but it's close. In research published in the journal Optica, University of California, Irvine researchers describe a new type of camera technology that, when aimed at an object, can rapidly ...

A new non-invasive technique for parchment diagnosis

The conservation state of parchments is typically assessed using invasive and sometimes destructive investigation techniques. Scientists from Université Paris-Saclay, the CNRS, École Polytechnique, and the French Ministry ...

When will your elevator arrive? Two physicists do the math

The human world is, increasingly, an urban one—and that means elevators. Hong Kong, the hometown of physicist Zhijie Feng (Boston University), adds new elevators at the rate of roughly 1500 every year...making vertical ...

Study suggests that silicon could be a photonics game-changer

New research from the University of Surrey has shown that silicon could be one of the most powerful materials for photonic informational manipulation—opening up new possibilities for the production of lasers and displays.
