Optical rotatum” is the term researchers coined to describe a newly discovered structure of light. Beams of light that can be ...

Near the starting line of this year’s Memorial Marathon, a massive laser known as The Architect will produce a beam of light ...

The findings were recently published in the journal Results in Optics. The scientists discovered that by coating a regular ...

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 ...

A beam of light doesn’t sound like a material that can create a knot. But it is. Imagine throwing several rocks into a pond all at once. At a certain point on the water’s surface, the ...
