Long range coupling within an ensemble of quantum dots by plasmonic nanostructures — •Laura Meißner1, Christian Dicken1, Michael Jetter2, and Markus Lippitz1 — 1Experimentalphysik III, Universität Bayreuth, 95440 Bayreuth, Germany — 2Institut für Halbleiteroptik und Funktionelle Grenzflächen, Universität Stuttgart,70569 Stuttgart, Germany
The dipole-dipole interaction between quantum emitters leads to well known effects such Dicke super-radiance of J aggregates. In a solid-state system, this interaction is weak due to its short range nature and the inhomogeneity of the ensemble. We investigate how a long-range surface plasmon can help to couple an ensemble of quantum dots. In a first approach, we combine high-density InP quantum dots with a two-dimensional surface plasmon forming at a gold layer. In this poster, we compare luminescence intensities and lifetimes as well as spatial emission patterns for different coupling geometries.
