Ultrasensitive Photoresponse of Graphene Quantum Dot in the Coulomb Blockade Regime to THz Radiation
E. Riccardi, S. Massabeau, F. Valmorra +11
Graphene quantum dots (GQDs) have recently attracted considerable attention, with appealing properties for terahertz (THz) technology. This includes the demonstration of large ther…
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…
Highly tunable hybrid metamaterials employing split-ring resonators strongly coupled to graphene surface plasmons
Peter Q. Liu, Isaac J. Luxmoore, Sergey A. Mikhailov +4
Metamaterials and plasmonics are powerful tools for unconventional manipulation and harnessing of light. Metamaterials can be engineered to possess intriguing properties lacking in…
InGaAs/AlInGaAs THz Quantum Cascade Lasers operating up to 195 K in strong magnetic field
Federico Valmorra, Giacomo Scalari, Keita Ohtani +2
Terahertz quantum cascade lasers based on InGaAs wells and quaternary AlInGaAs barriers were measured in magnetic field. This study was carried out on a four quantum well active re…
Ultrastrong Coupling in the Near-field of Complementary Split Ring Resonators
Curdin Maissen, Giacomo Scalari, Federico Valmorra +7
The ultrastrong light-matter interaction regime was investigated in metallic and superconducting complementary split ring resonators coupled to the cyclotron transition of two dime…
Strong coupling in the far-infrared between graphene plasmons and the surface optical phonons of silicon dioxide
Isaac. J. Luxmoore, Choon How Gan, Peter Q. Liu +4
We study plasmonic resonances in electrostatically gated graphene nanoribbons on silicon dioxide substrates. Absorption spectra are measured in the mid-far infrared and reveal mult…
Superconducting complementary metasurfaces for THz ultrastrong light-matter coupling
G. Scalari, C. Maissen, S. Cibella +5
A superconducting metasurface operating in the THz range and based on the complementary metamaterial approach is discussed. Experimental measurements as a function of temperature a…
