Enhanced Transmission in Rolled-up Hyperlenses utilizing Fabry-Peŕot Resonances
Jochen Kerbst, Stephan Schwaiger, Andreas Rottler +6
We experimentally demonstrate that the transmission though rolled-up metal/semiconductor hyperlenses can be enhanced at desired frequencies utilizing Fabry-Pérot resonances. By mea…
Transmission enhancement in three-dimensional rolled-up plasmonic metamaterials containing optically active quantum wells
Andreas Rottler, Stephan Schwaiger, Anuen Koitmäe +2
We investigate three-dimensional rolled-up metamaterials containing optically active quantum wells and metal gratings supporting surface plasmon polarition resonances. Finite-diffe…
Gain in Three-Dimensional Metamaterials utilizing Semiconductor Quantum Structures
Stephan Schwaiger, Matthias Klingbeil, Jochen Kerbst +8
We demonstrate gain in a three-dimensional metal/semiconductor metamaterial by the integration of optically active semiconductor quantum structures. The rolling-up of a metallic st…
Elementary excitations in charge-tunable InGaAs quantum dots studied by resonant Raman and resonant photoluminescence spectroscopy
Tim Köppen, Dennis Franz, Andreas Schramm +5
We report on resonant optical spectroscopy of self-assembled InGaAs quantum dots in which the number of electrons can accurately be tuned to N=0,1,2 by an external gate voltage. Po…
Anomalous magnetotransport and cyclotron resonance of high mobility magnetic 2DHGs in the quantum Hall regime
U. Wurstbauer, S. Knott, C. G. v. Westarp +5
Low temperature magnetotransport measurements and far infrared transmission spectroscopy are reported in molecular beam epitaxial grown two-dimensional hole systems confined in str…
Spin-wave interference in three-dimensional rolled-up ferromagnetic microtubes
Felix Balhorn, Sebastian Mansfeld, Andreas Krohn +4
We have investigated spin-wave excitations in rolled-up Permalloy microtubes using microwave absorption spectroscopy. We find a series of quantized azimuthal modes which arise from…
