Traditional lenses\u2014like the ones found in eyeglasses\u2014are 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, uses an array of tiny, connected waveguides that resembles a fishnet to focus light at wavelengths spanning from the visible to the infrared with record-breaking efficiencies.<\/p>\n

\n <\/section>\n

Unlike traditional lenses, the metalens is flat and compact and could be made small enough to fit inside increasingly miniaturized devices. The development could lead to game<\/a>-changing advances in solar energy, virtual reality technology<\/a>, medical imaging, information processing with light and other app<\/a>lications reliant upon optics.<\/p>\n

“We have overcome what was regarded as a fundamental roadblock,” said study principal investigator Boubacar Kant\u00e9, associate professor of electrical engineering and computer science<\/a>s at UC Berkeley and faculty scientist at Lawrence Berkeley National Laboratory. “This is, simply, the thinnest, most efficient, broadest band flat lens in the world.”
\nThe new technology, named the “Fishnet-Achromatic-Metalens (FAM),” is described in a study that appeared online June 25 in the journal Nature Communications<\/i>.
\nWhile many methods have been proposed to implement flat lenses over the past decade, the arrival of the new metalens is the first time this combination of properties has been achieved.
\nThe team demonstrated the ability of its fishnet-achromatic-metalens to capture 70% of incoming light in frequencies ranging from 640 nanometers (reddish-orange light) to 1,200 nanometers (infrared light). Light entering the fishnet metalens within that broad octave band of wavelengths would be focused at a single point on the other side of the lens.
\n“We are very excited by these results because many applications required the simultaneous processing of multiple wavelengths in a broad spectrum,” said Kant\u00e9. “This is the case for solar energy applications where we need to focus all colors of light for efficient solar cells or solar concentrators.”
\nA good next step, Kant\u00e9 said, would be to develop processes that could enable larger scale production.<\/p>\n
