In a lab at Osaka University, physicist Yoshiki Nakata and his colleagues fired a pulsed laser through a stack of three passive optical components and watched it shatter into 3,070 tiny, spinning ...

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 singularities. While they have been widely studied in recent decades, two ...

U.S. Naval Research Laboratory scientists from the Radio Astrophysics and Sensing Section of the Remote Sensing Division in conjunction with radio astronomers and engineers from the National Radio ...

TAMPA, Fla. — South Korea’s plans for a national security constellation are coming into sharper focus after a March 18 solar array supply deal set the stage for a first demonstrator as early as the ...

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 ...
