Enhanced Transmission in Rolled-up Hyperlenses utilizing Fabry-Pe\'rot Resonances
We experimentally demonstrate that the transmission though rolled-up
metal/semiconductor hyperlenses can be enhanced at desired frequencies
utilizing Fabry-P\'erot resonances. By means of finite difference time domain
simulations we prove that hyperlensing occurs at frequencies of high
transmission.Comment: 3 pages, 3 figure
Gain in Three-Dimensional Metamaterials utilizing Semiconductor Quantum Structures
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 structure on top of strained semiconductor layers
containing a quantum well allows us to achieve a three-dimensional superlattice
consisting of alternating layers of lossy metallic and amplifying gain
material. We show that the transmission through the superlattice can be
enhanced by exciting the quantum well optically under both pulsed or continuous
wave excitation. This points out that our structures can be used as a starting
point for arbitrary three-dimensional metamaterials including gain
