In a lab at Osaka University, physicist Yoshiki Nakata and his colleagues fired a pulsed laser through a stack of three ...

Researchers have developed a novel material using tiny organic crystals that convert light into a substantial mechanical force able to lift 1,000 times its own mass. Without the need for heat or ...

Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...

The latest research in ACS Applied Energy Materials has shown that vertically aligned silicon nanowire (VA-SiNW) arrays are capable of massively increasing light absorption and causing a significant ...

Light waves have a similar role in lidar to that of radio waves in radar: a lidar sensor sends out and receives information encoded in light pulses, and the system uses this information to make a map ...

Light enters a two-dimensional ring-resonator array from the lower left and exits at the lower right. Light that follows the edge of the array (blue) does not suffer energy loss and exits after a ...

Optogenetics, the technique in which light is used to either stimulate neurons to fire or prevent them from doing so, has had a dramatic impact in studies of the brain and behavior, but delivering ...
