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 ...

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).

A stand-out example of quantum weirdness is turning out to be surprisingly useful, as Margaret Harris explains ...

Space solar power, or what I like to call Starlink for electricity, is at once a ludicrous idea and a bit of a pipe dream.

Continental is unveiling its advanced laser beam scanning (LBS) technology designed for near-field projection applications in vehicles, offering ...

Femtosecond-long, petawatt-peak power beam could be used to probe previously inaccessible phenomena in materials science, ...

Precision sensor supplier Micro-Epsilon has extended its confocalDT range of confocal chromatic measurement systems with two ...

Chalmers University researchers unveil a novel optical amplifier with 300 nm bandwidth, enabling tenfold data rates for advanced laser systems and diagnostics.
