Phase-change metasurfaces integrate subwavelength optical architectures with materials whose refractive index and absorption can be dynamically and reversibly altered through an external stimulus, ...

Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, lightweight, flexible bandwidth adjustment, and non-mechanical movements.

Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Complex modulation of optical fields (i.e., the control of light’s amplitude and phase) is vital to the ...

Metalens is a kind of optical metasurface composed of metaatoms for manipulating incoming light's amplitude, phase, and polarization. Unlike traditional refractive lenses, metalens can modulate the ...
