Non-Invasive Near-field Spectroscopy of Single Sub-Wavelength Complementary Resonators
Lucy L Hale, Janine Keller, Thomas Siday +7
Subwavelength metallic resonators provide a route to achieving strong light-matter coupling by means of tight confinement of resonant electromagnetic fields. Investigation of such…
Superradiantly limited linewidth in complementary THz metamaterials on Si-membranes
Janine Keller, Johannes Haase, Felice Appugliese +6
We study complementary double split ring THz resonators fabricated on a 10 mum thin Si-membrane. The linewidths of the fundamental LC-mode and dipolar mode are drastically narrowin…
Limiting scattering processes in high-mobility InSb quantum wells grown on GaSb buffer systems
Ch. A. Lehner, T. Tschirky, T. Ihn +4
We present molecular beam epitaxial grown single- and double-side -doped InAlSb/InSb quantum wells with varying distances down to 50 nm to the surface on GaSb metamorphic buffer…
Magneto-transport controlled by Landau polariton states
Gian L. Paravicini-Bagliani, Felice Appugliese, Eli Richter +10
Hybrid excitations, called polaritons, emerge in systems with strong light-matter coupling. Usually, they dominate the linear and nonlinear optical properties with applications in…
Landau polaritons in highly non-parabolic 2D gases in the ultra-strong coupling regime
Janine Keller, Giacomo Scalari, Felice Appugliese +11
We probe ultra-strong light matter coupling between metallic terahertz metasurfaces and Landau-level transitions in high mobility 2D electron and hole gases. We utilize heavy-hole…
Influence of the magnetic field on the plasmonic properties of transparent Ni anti-dot arrays
Emil Melander, Erik Östman, Janine Keller +8
Extraordinary optical transmission is observed due to the excitation of surface plasmon polaritons (SPPs) in 2-Dimensional hexagonal anti-dot patterns of pure Ni thin films, grown…
