The integration of beam splitters and grating structures is central to contemporary developments in optical engineering. These devices, which manipulate light via diffraction and interference, are ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Reflective ruled diffraction grating is a kind of optical glass substrate composed of dense, equidistant parallel lines, and the surface is coated with aluminized, multi-layer dielectric or other ...

Be it sensors, cameras, or displays: Metasurfaces have the potential to fundamentally improve optical systems in our everyday lives. By controlling light more precisely, they drive compact, ...
