FDTD Simulations on three-dimensional plasmonic metamaterials containing optically active quantum wells — •Andreas Rottler, Malte Harland, Stephan Schwaiger, Aune Koitmäe, Detlef Heitmann, and Stefan Mendach — Institute of Applied Physics, University of Hamburg, Germany

Rolled-up metal/semiconductor multilayers containing optically active quantum wells opened up a new path for loss reduction in three dimensional metamaterials [1]. Recently, it was also shown that the embedding of plasmonic structures into these metamaterials can result in pumping induced transparency [2].

In this contribution we report on our recent finite-difference time-domain simulations on metamaterials consisting of alternating layers of plasmonic silver gratings and optically active semiconductor quantum wells. We investigated structure-design improvements in order to reduce the pumping power that is needed for optical net-gain.
