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 ...

MIT researchers built a photonic chip that launches thousands of laser beams into free space, enabling scalable quantum control.

Ever since America escaped the tyranny of the round and rectangular sealed beams, there's been continuous and determined progress in the field of seeing at night with your car. We've gone from ...
