Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...

At the intersection of nanotechnology and optics lies plasmonics, a specialized field that explores the intricate interactions between electromagnetic field waves and free electrons on metal surfaces.

New observation could provide way to increase the strength of interaction between light and matter, eventually leading to smaller lasers and other improved photonic technologies UNIVERSITY PARK, Pa. — ...

The interaction of silver materials with light is well-known as the basis of film photography. But, there are much more sophisticated interactions when we consider very, very small particles of silver ...

Physicists have long theorized the existence of a unique state of matter known as a quantum spin liquid. In this state, magnetic particles do not settle into an orderly pattern, even at absolute zero ...

Nano-optics, by bridging the gap between classical optics and nanotechnology, explores light at dimensions smaller than its wavelength. It leverages phenomena like plasmonics, near-field optics, and ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

Imagine supercomputers that think with light instead of electricity. That s the breakthrough two European research teams have made, demonstrating how intense laser pulses through ultra-thin glass ...

Scientists enable excitons to surpass light to transform materials and open new advanced paths to quantum devices.
