Near-field optics operates on the principle that when light interacts with objects smaller than its wavelength, it can produce an evanescent wave that decays exponentially with distance but provides ...

(Nanowerk News) Led by Prof. Wei Yayi, a team of researchers from the University of Chinese Academy of Sciences (UCAS) has achieved a significant breakthrough in enhancing the final pattern fidelity ...

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 ...

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.

Near-field optical trapping has transformed particle manipulation in biology, chemistry, and nanotechnology, enabling contact-free control of objects ranging from nanoparticles to living cells.

Optical trapping is a powerful tool for manipulating microscopic particles, but conventional approaches often suffer from limited trapping range and ...

Atomically thin semiconductors such as tungsten disulfide (WS2) are promising materials for future photonic technologies.

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., ...
