    Polaritons with hyperbolic dispersion are key to many emerging photonic technologies, including subdiffraction imaging, sensing and spontaneous emission engineering1, 2, 3, 4, 5, 6, 7, 8. Fundamental to their effective ...
  • Highly confined low-loss plasmons in graphene–boron nitride heterostructures 

    Woessner, Achim; Lundeberg, Mark B.; Gao, Yuanda; Principi, Alessandro; Alonso-González, Pablo; Carrega, Matteo; Watanabe, Kenji; Taniguchi, Takashi; Vignale, Giovanni; Polini, Marco; Hone, James; Hillenbrand, Rainer; Koppens, Frank H.L. (Nature Publishing Group, 2014-12-22)
    Article
    Open Access
    Graphene plasmons were predicted to possess simultaneous ultrastrong field confinement and very low damping, enabling new classes of devices for deep-subwavelength metamaterials, single-photon nonlinearities, extraordinarily ...
  • Thermoelectric detection and imaging of 1 propagating graphene plasmons 

    Lundeberg, Mark B.; Gao, Yuanda; Woessner, Achim; Tan, Cheng; Alonso-González, Pablo; Watanabe, Kenji; Taniguchi, Takashi; Hone, James; Hillenbrand, Rainer; Koppens, Koppens (Nature, 2016-09-19)
    Article
    Open Access
    Controlling, detecting and generating propagating plasmons by all-electrical means is at the heart of on-chip nano-optical processing1, 2, 3. Graphene carries long-lived plasmons that are extremely confined and controllable ...
