Efficient infrared sunlight absorbers based on gold-covered, inverted silicon pyramid arrays
Jinhui Hu, Luis A. Pérez, Juan Luis Garcia-Pomar +4
The transparency of silicon in the infrared region enables the design of nano/microstructures for implementation in devices to harvest the infrared (IR) part of the solar spectrum.…
Towards loss compensated and lasing terahertz metamaterials based on optically pumped graphene
Peter Weis, Juan Luis Garcia-Pomar, Marco Rahm
It is evidenced by numerical calculations that optically pumped graphene is suitable for compensating inherent loss in terahertz (THz) metamaterials. In a first step, the complex c…
Scattering of Graphene plasmons by defects in the graphene sheet
Juan L. Garcia-Pomar, Alexey Yu. Nikitin, Luis Martin-Moreno
A theoretical study is presented on the scattering of graphene surface plasmons by defects in the graphene sheet they propagate in. These defects can be either natural (as domain b…
Hybridization Induced Transparency in composites of metamaterials and atomic media
Peter Weis, Juan Luis Garcia-Pomar, René Beigang +1
We report hybridization induced transparency (HIT) in a composite medium consisting of a metamaterial and a dielectric. We develop an analytic model that explains HIT by coherent c…
Nonlinearity and optical bistability caused by local field effects in the interaction between a two level atomic system and a metamaterial
J. L. Garcia-Pomar, R. Beigang, M. Rahm
We present a theoretical analysis of the nonlinear response of a metamaterial consisting of an array of split ring resonators coupled to a two level atomic system (2LS) without inv…
Toy model for plasmonic metamaterial resonances coupled to two-level system gain
Martin Wegener, Juan Luis Garcia-Pomar, Costas M. Soukoulis +3
We propose, solve, and discuss a simple model for a metamaterial incorporating optical gain: A single bosonic resonance is coupled to a fermionic (inverted) two-level-system resona…
