Optical metamaterials to impact lens market ‘within a year’

2021.06.17 / By admin

Optical metamaterials are ready for initial commercial deployment and will command a market worth several billion dollars by 2030.

Those are two of the main conclusions from the latest market report on the emerging optics and photonics technology compiled by analysts at US consultancy Lux Research.

Authors Anthony Vicari and Michael Holman say that rapid maturation of the technology, which uses precisely controlled nanostructures to manipulate visible light, means that commercialization is imminent.

“A growing number of startups are forming, and large corporations are showing significant interest, including partnerships, investments, and product launches from Lockheed Martin, Intel, 3M, Edmund Optics, Airbus, Applied Materials, and TDK,” they suggest.

“Optical metamaterials will impact niches within the lens market in the next year,” added lead author Vicari. “Lack of production infrastructure and of device designers familiar with the technology have held back progress so far, but design and production technologies have matured rapidly in the past few years.”

While metamaterials have already started to make an impact in the radio and microwave spectrum – aided by the emergence of applications in 5G networks – the additional complexity of designs needed for higher-frequency operation has held back their visible-range counterparts thus far.

Attention initially focused on exotic ideas such as “invisibility cloaks” in the optical spectrum, but there is enormous market potential in more prosaic applications taking advantage of the ability to manipulate light with greater control than is possible with conventional optics.

With greater control over the direction, transmission, and focusing of light on all major performance axes, metamaterial devices are able to deliver novel capabilities including negative, tunable, and complex refractive indices.

They can also combine multiple optical functions, such as higher-order image corrections, in a single device layer, making for thinner and lighter products.

The Lux Research report identifies four key features that define the new technology. These include the ability to make optical components much thinner and lighter; the use of digital patterning for much faster product design; wavelength-specific devices; and much greater design freedom.

“Optical metamaterials will provide a performance advantage and competitive edge to early adopters that will drive accelerating growth as they substitute and supplement conventional optics,” write Vicari and Holman.

They see the most valuable markets appearing in cell phone cameras and corrective lenses, and say that although it will take time for optical metamaterials to scale up to the volumes demanded by such applications, a wide range of relatively niche applications will provide plenty of demand in the meantime.

“Though production costs are falling rapidly, they are still too high, and production scale too small, for many applications,” states the report. “In addition, there are only a handful of leading developers of this technology, which may become a bottleneck for innovation and adoption in the near term.”
