Ground state exciton-polariton condensation by coherent Floquet driving
Alexander Kuznetsov, Ignacio Carraro-Haddad, Gonzalo Usaj +3
The on-demand selective population transfer between states in multilevel quantum systems is a challenging problem with implications for a wide-range of physical platforms including…
Near-room-temperature zero-dimensional polariton lasers with sub-10 GHz linewidths
Ismael dePedro-Embid, Alexander S. Kuznetsov, Klaus Biermann +2
Narrow and brilliant spectral lines are essential assets for high-resolution spectroscopy as well as for precision sensing and optomechanics. In semiconductor structures and, in pa…
Shapiro resonances in ac-self-modulated exciton-polariton Josephson junctions
I. Carraro Haddad, D. L. Chafatinos, A. A. Reynoso +6
We experimentally investigate the dynamics of exciton polariton Josephson junctions when the coupling between condensates is periodically modulated through self-induced mechanical…
Optical anisotropies of asymmetric double GaAs (001) Quantum Wells
O. Ruiz-Cigarrillo, L. F. Lastras-Martínez, E. A. Cerda-Méndez +7
In the present work, we were able to identify and characterize a new source of in-plane optical anisotropies (IOAs) occurring in asymmetric DQWs; namely a reduction of the symmetry…
Spatial patterns of dissipative polariton solitons in semiconductor microcavities
J. K. Chana, M. Sich, F. Fras +9
Semiconductor microcavities operating in the polaritonic regime are highly non-linear, high speed systems due to the unique half-light, half-matter nature of polaritons. Here, we r…
Ultrafast supercontinuum fiber-laser based pump-probe scanning MOKE microscope for the investigation of electron spin dynamics in semiconductors at cryogenic temperatures with picosecond time and micrometer spatial resolution
T. Henn, T. Kiessling, W. Ossau +3
We describe a two-color pump-probe scanning magneto-optical Kerr effect (MOKE) microscope which we have developed to investigate electron spin phenomena in semiconductors at cryoge…
Effect of Interactions on Vortices in a Non-equilibrium Polariton Condensate
D. N. Krizhanovskii, D. M. Whittaker, R. A. Bradley +9
We demonstrate the creation of vortices in a macroscopically occupied polariton state formed in a semiconductor microcavity. A weak external laser beam carrying orbital angular mom…
The effects of spin-dependent interactions on polarisation of bright polariton solitons
M. Sich, F. Fras, J. K. Chana +10
We report on the spin properties of bright polariton solitons supported by an external pump to compensate losses. We observe robust circularly polarised solitons when a circularly…
Effect of polariton-polariton interactions on the excitation spectrum of a non-equilibrium condensate in a periodic potential
D. N. Krizhanovskii, E. A. Cerda, S. S. Gavrilov +9
Polariton condensates are investigated in periodical potentials created by surface acoustic waves using both resonant and non-resonant optical excitation. Under resonant pumping co…
Observation of bright polariton solitons in a semiconductor microcavity
M. Sich, D. N. Krizhanovskii, M. S. Skolnick +7
Microcavity polaritons are composite half-light half-matter quasi-particles, which have recently been demonstrated to exhibit rich physical properties, such as non-equilibrium Bose…
