Nanometric Ge Films for Ultrafast Modulation of THz Waves with Flexible Metasurface (Advanced Optical Materials 36/2024)

Year: 2024

Type: article

Abstract: Nanometric Ge Films for Ultrafast THz Modulation Nanometric germanium films, vastly thinner than terahertz wavelengths, have been integrated with a responsive metasurface of metallic terahertz asymmetric split ring resonators on a low-loss flexible substrate (cyclic olefin copolymer film). These ultrathin, flexible, and ultrafast functional metasurfaces enable efficient, low-power terahertz modulation. For further information, see article number 2402010 by Jianqiang Gu, Ranjan Singh, and co-workers.
