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…
Magnetic anisotropy in (Ga,Mn)As: Influence of epitaxial strain and hole concentration
M. Glunk, J. Daeubler, L. Dreher +8
We present a systematic study on the influence of epitaxial strain and hole concentration on the magnetic anisotropy in (Ga,Mn)As at 4.2 K. The strain was gradually varied over a w…
Advanced resistivity model for arbitrary magnetization orientation applied to a series of compressive- to tensile-strained (Ga,Mn)As layers
W. Limmer, J. Daeubler, L. Dreher +4
The longitudinal and transverse resistivities of differently strained (Ga,Mn)As layers are theoretically and experimentally studied as a function of the magnetization orientation.…
