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 ...

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).

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 ...

A discrete core-shell-like micro-light-emitting diode (micro-LED) array was grown on a 100 nm-thick sapphire nano-membrane array without harmful plasma etching for chip singulation. Due to proper ...

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 ...

Large-area grown GaN microdisk arrays on graphene microdots were used as a starting material for the fabrication of free-standing, ultrathin LED arrays. The first step was to transfer parts of the GaN ...

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 ...

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 ...
