    Two thin flakes of niobium oxide dichloride stacked on each other and photographed under a light microscope. One flake’s crystalline grain (gray flake) is positioned perpendicularly to the grain of the other flake (green flake).
    FIGURE 1. Depiction of the ultrahigh-density optical memory. Red dots represent rare earth ion impurities, and blue dots represent defects onto which the excitation is stored by using near-field energy transfer processes. Many optically addressable RE ions within the diffraction-limited excitation volume (red beam) result in an enhanced bit density.

    FIGURE 1. A THz electrical input pulse (with a pulse width of 1.2 picoseconds) was applied to graphene on a chip to generate and propagate a graphene plasmon wave packet, and its real-time waveform was measured with subpicosecond temporal resolution (hBN: hexagonal boron nitride).
