      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 ...

    • Fast and sensitive terahertz detection using an antenna-integrated graphene pn-junction 

      Castilla, Sebastián; Terrés, Bernat; Autore, Marta; Viti, Leonardo; Li, Jian; Nikitin, Alexey Y.; Vangelidis, Ioannis; Watanabe, Kenji; Taniguchi, Takashi; Lidorikis, Elefterios; Vitiello, Miriam S.; Hillenbrand, Rainer; Tielrooij, Klaas-Jan; Koppens, Frank H. L. (ACS, 2019-03-18)
      Article
      Open Access
      Although the detection of light at terahertz (THz) frequencies is important for a large range of applications, current detectors typically have several disadvantages in terms of sensitivity, speed, operating temperature, ...

    • 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 ...

    • Phonon-Enhanced Mid-Infrared CO2 Gas Sensing Using Boron Nitride Nanoresonators 

      Bareza, Nestor Jr.; Paulillo, Bruno; Slipchenko, Tetiana M.; Autore, Marta; Dolado, Irene; Liu, Song; Edgar, James H.; Vélez, Saül; Martín-Moreno, Luis; Hillenbrand, Rainer; Pruneri, Valerio (ACS, 2022-01-05)
      Article
      Open Access
      Hexagonal boron nitride (hBN) hosts long-lived phonon polaritons, yielding a strong mid-infrared (mid-IR) electric field enhancement and concentration on the nanometer scale. It is thus a promising material for highly ...

    • 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, Frank H. L. (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 ...
