Coupling Dynamics and Linear Polarization Phenomena in Codirectional Polariton Waveguide Couplers
Elena Rozas, Alexey Yulin, Sebastian Klembt +3
In this work, we explore the potential of spin-based integrated devices using polariton waveguides that form codirectional couplers. For suitable coupler parameters, a transfer of…
Continuous-variable quantum optics and resource theory for ultrafast semiconductor spectroscopy
Carolin Lüders, Franziska Barkhausen, Matthias Pukrop +4
In this review, we discuss the use of continuous variable spectroscopy techniques for investigating quantum coherence and light-matter interactions in semiconductor systems with ul…
Polariton-dark exciton interactions in bistable semiconductor microcavities
Elena Rozas, Evgeny Sedov, Yannik Brune +3
We take advantage of the polariton bistability in semiconductor microcavities to estimate the interaction strength between lower exciton-polariton and dark exciton states. We combi…
Effects of the linear polarization of polariton condensates in their propagation in codirectional couplers
Elena Rozas, Alexey Yulin, Johannes Beierlein +9
We report on the linear polarization of polariton condensates in a codirectional coupler that allows evanescent coupling between adjacent waveguides. We observe polarization-depend…
On the remote coherence of polariton condensates in 1D microcavities: a photoluminescence study
M. D. Martín, E. Rozas, C. Antón +2
In this manuscript we will gather clear experimental evidences of remote coherence between two polariton condensate droplets that have never overlapped in real space and discuss ho…
Impact of the energetic landscape on polariton condensates propagation along a coupler
E. Rozas, J. Beierlein, A. Yulin +10
Polariton condensates propagation is strongly dependent on the particular energy landscape the particles are moving upon, in which the geometry of the pathway laid for their moveme…
Propagative oscillations in co-directional polariton waveguide couplers
J. Beierlein, E. Rozas, O. A. Egorov +12
We report on novel exciton-polariton routing devices created to study and purposely guide light-matter particles in their condensate phase. In a co-directional coupling device, two…
Direct observation of photonic Landau levels and helical edge states in strained honeycomb lattices
O. Jamadi, E. Rozas, G. Salerno +9
We report the realization of a synthetic magnetic field for photons and polaritons in a honeycomb lattice of coupled semiconductor micropillars. A strong synthetic field is induced…
Counter-directional polariton coupler
M. Klaas, J. Beierlein, E. Rozas +10
We report on an on-chip routing device for propagating condensates of exciton-polaritons. This counterdirectional coupler implements signal control by a photonic microdisk potentia…
Determination of polariton condensates' critical temperature
E. Rozas, M. D. Martín, C. Tejedor +4
We investigate the thermal robustness of traveling polariton condensates. We create remote condensates that have never been in contact, and study their interference in momentum spa…
Temperature dependence of the coherence in polariton condensates
E. Rozas, M. D. Martín, C. Tejedor +4
We present a time-resolved experimental study of the temperature effect on the coherence of traveling polariton condensates. The simultaneous detection of their emission both in re…
