    Full 2π tunable phase modulation using avoided crossing of resonances

    Active metasurfaces have been proposed as one attractive means of achieving high-resolution spatiotemporal control of optical wavefronts, having applications such as LIDAR and dynamic holography. However, achi...

    Real-space imaging of acoustic plasmons in large-area graphene grown by chemical vapor deposition

    An acoustic plasmon mode in a graphene-dielectric-metal structure has recently been spotlighted as a superior platform for strong light-matter interaction. It originates from the coupling of graphene plasmon w...
