Gain and plasmon dynamics in negative-index metamaterials
Sebastian Wuestner, Andreas Pusch, Kosmas L. Tsakmakidis +2
Photonic metamaterials allow for a range of exciting applications unattainable with ordinary dielectrics. However, the metallic nature of their meta-atoms may result in increased o…
Evanescent Gain in "Trapped Rainbow" Negative Refractive Index Heterostructures
Edmund I. Kirby, Joachim M. Hamm, Tim Pickering +2
We theoretically and numerically analyze a five-layer "trapped rainbow" waveguide made of a passive negative refractive index (NRI) core layer and gain strips in the cladding. Anal…
Overcoming losses with gain in a negative refractive index metamaterial
Sebastian Wuestner, Andreas Pusch, Kosmas L. Tsakmakidis +2
On the basis of a full-vectorial three-dimensional Maxwell-Bloch approach we investigate the possibility of using gain to overcome losses in a negative refractive index fishnet met…
