A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of ...

More generally, a variety of metallic plasmonic nano-antennas have the ability to concentrate light into a volume much smaller than that derived from the diffraction limit. If these nano-antennas ...

Another way to see this is by looking at a point source of light through the maple leaf; this works with the naked eye. Turn off the lights ... banknotes in circulation don't have the maple leaf ...

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 ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...

Metasurfaces have the potential to fundamentally improve optical systems in our everyday lives. By controlling light more precisely, they drive compact, multi-functional solutions. Researchers have ...
