Atomic-scale detail is now possible with photons, thanks to a cooled-down silver tip and a clever use of plasmonics.

Researchers have developed a new microscope that can visualize the optical response of surfaces at an unprecedented spatial ...

Understanding the interaction between light and matter at the smallest scales (angstrom scale) is essential for advancing ...

Optical cavities are highly sensitive to changes in their environment, making them ideal for sensing applications. Cavity-enhanced sensing techniques, such as cavity ring-down spectroscopy (CRDS) and ...

In the photograph of NGC 1068, a spiral galaxy with a black hole at the center, Chandra’s X-rays are responsible for the blue coloring in the image. Optical photographs from both Hubble and Webb add ...

BUFFALO, N.Y. – Associated with unhappy visits to the dentist, “cavity” means something else in the branch of physics known as optics. Put simply, an optical cavity is an arrangement of mirrors that ...

Light can only pass through the cavity when it is in resonance with the cavity. These have been around since 1899, so they aren’t that exotic. In fact, they are often used in laser communication ...

Inside the optical cavity, light particles emerge and disappear. These fluctuations can change the magnetic order of α-RuCl 3 from a zigzag antiferromagnet into a ferromagnet. Researchers in ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.

A newly designed optical cavity selectively enhances quantum vacuum fluctuations of circularly polarized light in one direction, achieving chirality with minimal magnetic fields.
