But metalenses—a new class of ultra-thin lenses built from nanoscale structures—are now changing the rules. Metalenses use nanostructures, often smaller than the wavelength of light, to steer ...

Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Skip to main content. Your source for the latest research news.

Ultra-thin lithium niobate metalenses with engineered nanostructures can halve the wavelength of incident light, converting infrared (800 nm) to visible (400 nm) while focusing it.

Ultra-thin lenses that generate new light. Using this technique, the ETH researchers in Grange's group succeeded in creating the first lithium niobate metalenses with precisely engineered ...
