(Upper panel) Experimental scheme. When a chiral gold nanoparticle is illuminated with near-infrared linearly polarized femtosecond light pulses, circularly polarized luminescence is observed in the ...

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 ...

Changing light's polarization can reverse the structure of a patterned light field, opening a new way to control geometry and information in optics. (Nanowerk Spotlight) Light can be bent, focused, or ...

A device produces green light while a researcher in lab gear stands in the background. This OLED device, which is held by a mechanical support, is producing circularly polarized light. Credit: ...
