Dispersion is an inherent feature of electromagnetic waves. It allows light to behave differently at different wavelengths, which can be useful, but it also creates chromatic aberrations. As bandwidth ...

Cameras are everywhere. For over two centuries, these devices have grown increasingly popular and proven to be so useful, they have become an indispensable part of modern life. Subscribe to our ...

(Nanowerk Spotlight) Quantum light sources are a fundamental building block for many quantum technologies, enabling secure communication, powerful computing, and precise sensing and imaging.

This Collection welcomes original research articles on flat optics, with a focus on the design, fabrication, and characterisation of planar optical elements. It also highlights emerging applications ...

A research team has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. The study not only identifies the constraints of conventional sampling theories in ...

To control light, curved lenses are used today, that are often made of glass that is either concave or convex, which refracts the light in different ways. These types of lenses can be found in ...

This paper covers a discussion of the Abbe Sine Condition and its implication for Flat Optics, including the effects of stop shift and substrate curvature. Following that, we apply Sweatt’s high index ...

Researchers found silica can outperform high-index materials for optical metasurfaces. Its chip-making compatibility enables scalable, robust flat optical devices. (Nanowerk News) An unexpected ...

Flat optics are made of nanostructures containing high-refractive index materials to produce lenses with thin form factors that function only at specific wavelengths. Researchers from Skoltech, the ...

NIL Technology (NILT), a developer of flat optics, announced this week that it has raised €29 million in new capital. The investment in the Denmark-based firm was led by a syndicate of investors ...

Optical Surfaces Ltd. is a leading manufacturer of large, high precision optical flats and coated flat mirrors including a range of non-circular shapes such as elliptical and octagonal. When the ...
