Quantum Mollow Quadruplet in Non-linear Cavity-QED
Thomas Allcock, Wolfgang Langbein, Egor Muljarov
We develop an exact analytical approach to the optical response of a quantum dot-microcavity system for arbitrary excitation strengths. The response is determined in terms of the c…
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…
Microcavity polariton-like dispersion doublet in resonant Bragg gratings
Fabio Biancalana, Leonidas Mouchliadis, Celestino Creatore +2
Periodic structures resonantly coupled to excitonic media allow the existence of extra intragap modes ('Braggoritons'), due to the coupling between Bragg photon modes and 3D bulk e…
Microscopic measurement of photon echo formation in groups of individual excitonic transitions
Wolfgang Langbein, Brian Patton
The third-order polarization emitted from groups of individual localized excitonic transitions after pulsed optical excitation is measured. We observe the evolution of the nonlinea…
Quantum complementarity of microcavity polaritons
Salvatore Savasta, Omar Di Stefano, Vincenzo Savona +1
We present an experiment that probes polariton quantum correlations by exploiting quantum complementarity. Specifically, we find that polaritons in two distinct idler-modes interfe…
