Control and Dynamic Competition of Bright and Dark Lasing States in Active Nanoplasmonic Metamaterials
Sebastian Wuestner, Joachim M. Hamm, Andreas Pusch +3
Active nanoplasmonic metamaterials support bright and dark modes that compete for gain. Using a Maxwell-Bloch approach incorporating Langevin noise we study the lasing dynamics in…
Theory of light amplification in active fishnet metamaterials
Joachim M. Hamm, Sebastian Wuestner, Kosmas L. Tsakmakidis +1
We establish a theory that traces light amplification in an active double-fishnet metamaterial back to its microscopic origins. Based on ab initio calculations of the light/plasmon…
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…
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…
