Researchers have developed a new microscope that can visualize the optical response of surfaces at an unprecedented spatial resolution of one nanometer. This paves the way for optical microscopy of ...

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 ...

Penetrating ever farther into the submicron world, microscope designers have broken through the diffraction barrier that once stood between researchers and the mysterious depths of the nano world.

Researchers from Regensburg and Birmingham have overcome a fundamental limitation of optical microscopy. With the help of quantum mechanical effects, they succeeded for the first time in performing ...

The optical field with sub-nanometer confinement can greatly enhance light-matter interactions at nanoscale (e.g., enabling forbidden atomic transitions) and push extreme optical technologies (e.g., ...
