In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

An LED and a semiconductor laser (or laser LED) work in essentially the same way, that is, light is emitted as electrons and holes combine, with emission wavelength dependent upon the materials used.

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

Using geometric phase inside lasers for the first time, researchers find a way to change the orbital angular momentum of laser beams. Nature Photonics today published research by a team from South ...

Appotronics has unveiled its new Laser+LCoS optical engine prototype for AR glasses, offering advantages over microLED-based modules | AR News from Auganix.org ...

When we think about the onward march of automotive technology, headlights aren’t usually the first thing that come to mind. Engines, fuel efficiency, and the switch to electric power are all more ...
