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 ...

Miniaturized and multicolored light-emitting device arrays provide a promising instrument to sense, image and compute in materials science and applied physics. A range of emission colors can be ...

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 lower image is an illustration of the optical phased array, while the upper two panels are scanning electron microscope images of the array (left) and an individual element of the array (right).

The light array features opto-mechanical alignment with bright red emitter beams spaced 70 mm apart for easy set-up and installation. To ensure effective light-guided assembly in diverse applications, ...

One of the challenges of optical microscopy is to continually increase the imaging power, or resolution. In the past three hundred odd years, scientists have been building ever-better microscopes. The ...

H. Y. Fu is in the Tsinghua Shenzhen International Graduate School, Tsinghua University, Shenzhen 518055, China. Light waves have a similar role in lidar to that of radio waves in radar: a lidar ...

It was not too long ago that basic science lectures began with the three forms of matter: gases, liquids and solids—and somewhere along the line plasmas were occasionally added to the list. But to be ...

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 ...
