A team of photonics and electronic engineers at Kyoto University has found a way to overcome the shortcomings of photonic-crystal surface-emitting lasers (PCSELs) that have prevented their use in industrial-scale cutting ...
In the realm of photonics, the integration of multiple optical devices onto a single substrate holds immense promise for a wide range of applications. This revolutionary approach, known as photonic integration, offers remarkable ...
Researchers at MPQ in Garching, together with a team from TU Munich, have excited erbium atoms embedded in crystalline silicon such that they emit single photons. Their special properties can form the basis for the development ...
Â鶹ÒùÔºicists at the University of Konstanz have generated one of the shortest signals ever produced by humans: Using paired laser pulses, they succeeded in compressing a series of electron pulses to a numerically analyzed duration ...
Using a complex cast of metal-studded pigments, proteins, enzymes, and co-enzymes, photosynthetic organisms can convert the energy in light into the chemical energy for life. And now, thanks to a study published June 14 in ...
We've all played at least once with a spring toy, but did you know that light can be shaped like a spring too?
New research findings on the gamma-ray burst (GRB) named GRB 221009A from the Large High Altitude Air Shower Observatory (LHAASO) were published online by the journal Science on June 8, 2023. The study, titled "A tera-electron ...
In everyday life we experience light in one of its simplest forms—optical rays or beams. However, light can exist in much more exotic forms. Thus, even beams can be shaped to take the form of spirals; so-called vortex beams, ...
New findings from a team of researchers at MIT and elsewhere could help pave the way for new kinds of devices that efficiently bridge the gap between matter and light. These might include computer chips that eliminate inefficiencies ...
Cellulose nanocrystal (CNC), an emerging bio-based material, has been widely applied in fields such as electronics, bioplastics and energy. However, the functional failure of such materials in wet or liquid environments inevitably ...
