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.

Physicists at ETH Zurich have developed an ultra-thin lens capable of converting infrared light into visible wavelengths. This breakthrough, achieved using lithium niobate metasurfaces, could ...
