For the first time, researchers have used high-speed laser writing to create lines spaced just 100 nm apart on a glass ...

Optical computing is a proposed solution to increase speed and power efficiency but has yet to be realized due to constraints ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

The emergence of imaging schemes capable of overcoming Abbe's diffraction barrier is revolutionizing optical microscopy. In 1873, the German physicist Ernst Abbe realized that the resolution of ...

Researchers developed a new optimized printing approach that could enable super-resolution 3D direct laser writing (DLW) of microlenses, photonics crystals, micro-optical devices, metamaterials and ...

Detailed in a paper just published in the journal Optics Express, the experimental setup uses a tellurium-doped fiber laser ...

Researchers achieved nanometer-scale resolution without requiring a dark state, expanding super-resolution imaging to ...
