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

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

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 ...

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 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 ...
