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 ...

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 ...

Inside most photonic chips, light races through tiny optical wires. It carries information far faster than electricity can in many conventional systems.

Now, adding a twisting laser beam that interacts with these electrons makes things even more complicated. And in that ...

Chinese projector maker XGIMI reckons it's come up with a best of both worlds solution for projector light sources by combining the high color fidelity and comfortable viewing experience of LED ...

A new type of laser is modeled after an exotic class of materials called topological insulators. And it’s proving more reliable and energy-efficient than its conventional counterparts, paving the way ...
