Light moving through a tiny silicon structure does not look dramatic. It slips down narrow waveguides etched onto a chip, ...

Inside most photonic chips, light races through tiny optical wires. It carries information far faster than electricity can in many conventional systems.

Asymmetric optical transmission refers to the engineered phenomenon whereby light propagates with different efficiencies in opposite directions within a photonic structure. This effect is achieved by ...

Electro-optical and photonic devices have made great progress in their level of integration and performance. However, they do ...

Researchers used their new technique to fold a glass bar (a), create an optical resonator (b) to achieve helical bending (c) and to create a table with a parabolic reflector (middle, lower row).

Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored ...

Photonic chips use light to process data instead of electricity, enabling faster communication speeds and greater bandwidth. Most of that light typically stays on the chip, trapped in optical wires, ...

Can light behave like a whirlwind? It turns out it can—and such "optical tornadoes" have now been created in an extremely ...

Nudibranchs are often referred to as the butterflies of the sea. Nudibranchs live worldwide, primarily in warm, shallow ...

(Nanowerk Spotlight) The vibrant blue of a morpho butterfly's wings doesn't come from pigments but from light interacting with microscopic structures on its surface. This phenomenon – structural color ...
