A near-field plate is helping researchers in the US to focus light well beyond its diffraction limit. With the ability to focus radiation ranging from microwaves to the UV, the device could have ...

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...

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 ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2023.220157 discusses lensless complex amplitude demodulation based on deep learning in holographic data storage. In the era of big data, ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240250, discusses on-chip multi-channel near-far field terahertz vortices with parity breaking and active modulation. Vortex ...
