Tunable Plasmonic Nanoantennas in Rolled-up Microtubes Coupled to Integrated Quantum Wells
Hoan Vu, Jan Siebels, David Sonnenberg +2
We propose and realize a tunable plasmonic nanoantenna design consisting of two stacked Ag cuboids that are integrated into a rolled-up semiconductor microtube. The antenna's reson…
Spin Wave Diffraction and Perfect Imaging of a Grating
S. Mansfeld, J. Topp, K. Martens +4
We study the diffraction of Damon-Eshbach-type spin waves incident on a one-dimensional grating realized by micro slits in a thin permalloy film. By means of time-resolved scanning…
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…
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…
