Broadband Nanostructure Hologram

metasurfaceResearchers demonstrate a helicity multiplexed metasurface hologram capable of achieving high efficiency and high image quality over a broadband in the visible and near infrared range, circumventing previous problems of low efficiency and poor image quality. This work paves the way for fabricating novel practical devices with switchable functionalities, leading to advances in areas such as microscopy, and information processing.
