A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240076 , discusses spin-controlled generation of a complete polarization set with randomly-interleaved plasmonic metasurfaces.

A new semipolar InGaN LED with an integrated metasurface produces circularly polarized light at 68% conversion efficiency, ...

Laser-assisted electron scattering was observed using circularly polarized femtosecond laser pulses in the near-infrared range, a first for this technique. Energy and angular distributions of ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...

LAES measurement using circularly polarized light. A femtosecond laser pulse and an electron pulse were fired at an argon gas beam at the same time, giving a scattering signal whose energy and angular ...

Ultrathin structures that can bend, focus, or filter light, "metasurfaces" are reshaping how scientists think about optics. These engineered materials offer precise control over light's behavior, but ...

Researchers have produced a record-thin optical quarter-waveplate from the two-dimensional material niobium oxychloride (NbOCl2), measuring roughly 269 nanometers thick and operating at a wavelength ...

The challenges of fabricating micromotors and geartrains with comparable size to a human cell. The problems of powering such motors. How metasurfaces allow projected laser output to power these ...

Researchers from the Institute for Molecular Science and Seoul National University have found that the visible luminescence from chiral gold nanoparticles, when exposed to near-infrared femtosecond ...
