    • Electrically defined topological interface states of graphene surface plasmons based on a gate-tunable quantum Bragg grating 
      Fan, Zhiyuan; Dutta-Gupta, Shourya; Gladstone, Ran; Trendafilov, Simeon; Bosch, Melissa; Jung, Minwoo; Iyer, Ganjigunte R. Swathi; Giles, Alexander J.; Shcherbakov, Maxim; Feigelson, Boris; Caldwell, Joshua D.; Allen, Monica; Allen, Jeffery; Shvets, Gennady (Nanophotonics, 2019-08)
      A periodic metagate is designed on top of a boron nitride-graphene heterostructure to modulate the local carrier density distribution on the monolayer graphene. This causes the bandgaps of graphene surface plasmon polaritons ...
    • Manipulation and Design of Phonon and Plasmon Polaritons 
      He, Mingze; 0000-0001-8773-1268 (2023-07-14)
      Department: Mechanical Engineering
      Due to the long free-space wavelengths associated with radiation in the infrared (IR), the realization of flat and sub-diffractional optical components promises advances in imaging, communications, sensing, and thermal ...
    • Phonon Polaritons for Engineering Thermal Emission and Heat Transfer 
      Lu, Guanyu; 0000-0001-8960-0464 (2023-03-14)
      Department: Mechanical Engineering
      The field of nanophotonics is based on the confinement of electromagnetic energy to length scales multiple orders of magnitude shorter than that of the free-space photon wavelength. In the infrared (IR) spectral region, ...
