Due to chromatic dispersion, conventional designs have required separate waveguide layers for red, green, and blue light—three to six stacked glass sheets—inevitably increasing both weight and ...

Traditional optical systems rely on bulky glass lenses ... cameras to more specialized applications in VR and AR. By solving the core issues of metalenses—chromatic and angular aberrations ...

Researchers have eliminated the need for multiple layers by developing an achromatic metagrating that handles all colors in a ...
