Researchers have designed an optical lens with the highest free-space numerical aperture to date, achieving a value of just under 1. As the numerical aperture indicates the highest possible resolution that a lens can attain, ...
Flat optics are made of nanostructures containing high-refractive index materials to produce lenses with thin form factors that function only at specific wavelengths.
Optical properties of materials are based on their chemistry and the inherent subwavelength architecture, although the latter remains to be characterized in depth. Photonic crystals and metamaterials have proven this by providing ...
An interdisciplinary team of researchers from Korea, Australia, Great Britain, and Germany—with participation of Leibniz Institute of Photonic Technology (Leibniz IPHT)—were able for the first time to optimize an optical ...
