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

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

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

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

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 ...

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 ...

Researchers from Regensburg and Birmingham overcome a fundamental limitation of optical microscopy. With the help of quantum mechanical effects, they succeed for the first time in performing optical ...

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, ...

Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar ...
