Record-breaking metalens could revolutionize optical technologies

Traditional lenses—like the ones found in eyeglasses—are bulky, heavy and only focus light across a limited number of wavelengths. A new, ultrathin metalens developed by researchers at the University of California, Berkeley, ...

Physicists create time-reversed optical waves

Optics researchers from The University of Queensland and Nokia Bell Labs in the US have developed a new technique to demonstrate the time reversal of optical waves, which could transform the fields of advanced biomedical ...
