Now researchers at Toshiba and their colleagues reveal that quantum communications are possible across more than 250 ...

What turned into a tradition started on April 22, 2017, when I hiked the Rock Creek Road to Eilertson Meadow. Rock Creek is ...

Light can tie knots—literally. Engineers at Duke University have managed to manipulate laser beams to form intricate 3D patterns called optical knots, using custom-designed optics. These twisted beams ...

Scientists have demonstrated a sort of holographic strip that splits a single laser beam into five bespoke beams that create an optical knot. The work shows that optical knots could be used as a ...

Upgrades and new research at Argonne National Laboratory are helping physicists push boundaries, from basic science to the ...

This study examines interferometric techniques for distance measurement, focusing on innovations that mitigate air turbulence and refractive index fluctuations.

VCSELs offer a third option compared with conventional light emitting diodes (LEDS) and edge-emitting laser diodes (EELs).
