    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).
    While the terahertz region remains largely unexplored, graphene plasmons present a unique pathway to reach new frontiers within terahertz-based signal processing.
