Metalens could be game-changer in optics

The researchers, who were led by applied physics and electrical engineering professor Federico Capasso, used an electron beam to create nanofins, or a structure made out of titanium dioxide. This structure has been compared to the “world’s smallest Stonehenge,” and when the small blocks in the structure are rotated in various angles, they are still able to pull light like conventional curved glass is capable of doing.

“We are reporting planar lenses … that operate at visible wavelengths, and the potential, we think, is huge to replace conventional lenses in a lot of applications,” said Capasso.

Using the nanofins mounted on non-focusing glass for optimum stability, the researchers found that the newly created metamaterial lens was sharper than a conventional 55mm microscope lens. The metalens also happens to be very, very compact in comparison to others. It measures only 600 nanometers thick — 100,000 times thinner than conventional lenses — and 2mm across. In practical application, this could potentially be used as a way for gadget makers to make their smartphones, cameras, or even microscopes even thinner than they already are.

It also bears mentioning the metamaterial lens is quite different from the glass lenses used in cameras and binoculars. The researchers used a thin transparent quartz layer, which was coated in millions of extremely thin pillars as illustrated above. The new lens could also reduce the number of aberrations that are very common in standard glass lenses, as the researchers noted.

“The quality of our images is actually better than with a state-of-the-art objective lens,” said Capasso, who is confident that his discovery could be a game-changer. “I think it is no exaggeration to say that this is potentially revolutionary.”

For those interested in the dollars-and-cents aspect of tech, Capasso said that the use of the lenses in cell phone cameras is a natural choice. Most of these phones’ features are made using chip architecture, and it could save time and money if these components and features also include the camera lens. And the technique could also allow any size of lens to be created; the researchers went with lenses measuring 2mm across due to limitations of their own manufacturing equipment.

“Once you have the foundry – you want a 12-inch lens? Feel free, you can make a 12-inch lens,” said Capasso. “There’s no limit.”
