For over a century, light has both helped and limited our view of the ...

The speed of light varies in materials, impacting fiber optics, laser systems, and semiconductor lithography through complex electromagnetic interactions.

Scientists achieve optical measurements at atomic scales using quantum electron tunneling, surpassing conventional microscopy limits by nearly 100,000 times with standard lasers.

Researchers from Regensburg and Birmingham have overcome a fundamental limitation of optical microscopy. With the help of ...

By squeezing terahertz light beyond its usual limits, researchers have exposed hidden quantum "jiggles" inside a ...

Those who have experienced method development for laser diffraction understand the scenario well: you are dealing with a new type of sample, uncertain about handling a particular detail, and the one ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

You can tell a lot about a material based on the type of light shining at it: Optical light illuminates a material's surface, ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used ...
