The diffraction of light is a ubiquitous phenomenon in nature where waves spread out as they propagate. This spreading of light beams during propagation limits the efficient transmission of energy and ...

An international team of physicists has achieved a significant advance in laser science, demonstrating for the first time a practical route to dramatically boosting the intensity of high-power laser ...

Be it sensors, cameras, or displays: Metasurfaces have the potential to fundamentally improve optical systems in our everyday lives. By controlling light more precisely, they drive compact, ...

Nanoscale features of a laser-driven light sail showing germanium pillars and air holes embedded in a poly(methyl methacrylate) matrix, designed to achieve high ...

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 ...

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 ...

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 ...

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 ...
