Parametric scattering of microcavity polaritons into ghost branches
Joanna M Zajac, Wolfgang Langbein
Polaritons of defined momentum and energy are excited resonantly on the lower polariton branch of a planar semiconductor microcavity in the strong coupling regime, and the spectral…
Structure and zero-dimensional polariton spectrum of natural defects in GaAs/AlAs microcavities
Joanna M Zajac, Wolfgang Langbein
We present a correlative study of structural and optical properties of natural defects in planar semiconductor microcavities grown by molecular beam epitaxy, which are showing a lo…
Brillouin-Wigner perturbation theory in open electromagnetic systems
E. A. Muljarov, W. Langbein, R. Zimmermann
A Brillouin-Wigner perturbation theory is developed for open electromagnetic systems which are characterised by discrete resonant states with complex eigenenergies. Since these sta…
Femtosecond phase-resolved microscopy of plasmon dynamics in individual gold nanospheres
Francesco Masia, Wolfgang Langbein, Paola Borri
The selective optical detection of individual metallic nanoparticles (NPs) with high spatial and temporal resolution is a challenging endeavour, yet is key to the understanding of…
