At high power, laser light inside a multimode optical fiber is supposed to misbehave. The beam usually breaks into a noisy, scattered pattern as the light ricochets through many paths at once.
Researchers at Texas A&M University have demonstrated micron-scale 'metajets' that can be lifted and steered in three dimensions using only laser light. The fuel-free propulsion concept relies on ...
Researchers at Texas A&M University have demonstrated 'metajets'—microscopic devices propelled and steered in three dimensions by laser light. Built from nanoscale metasurfaces, the devices embed ...
