Formation dynamics of exciton polariton vortices created by non-resonant annular pumping
Bernd Berger, Daniel Schmidt, Xuekai Ma +4
We study the spontaneous formation of exciton polariton vortices in an all-optical non-resonantly excited annular trap, which is formed by ring-shaped subpicosecond laser pulses. S…
Realization of all-optical vortex switching in exciton-polariton condensates
Xuekai Ma, Bernd Berger, Marc Assmann +5
Vortices are topological objects representing the circular motion of a fluid. With their additional degree of freedom, the 'vorticity', they have been widely investigated in many p…
Spectroscopy of fractional orbital angular momentum states
Bernd Berger, Marius Kahlert, Daniel Schmidt +1
We present an approach for measuring the orbital angular momentum (OAM) of light tailored towards applications in spectroscopy and non-integer OAM values. It is based on the OAM so…
Tracking Dark Excitons with Exciton Polaritons in Semiconductor Microcavities
Daniel Schmidt, Bernd Berger, Marius Kahlert +6
Dark excitons are of fundamental importance for a wide variety of processes in semiconductors, but are difficult to investigate using optical techniques due to their weak interacti…
Dynamics of the Optical Spin Hall Effect
Daniel Schmidt, Bernd Berger, Manfred Bayer +6
We study the time evolution of the Optical Spin Hall Effect (OSHE), which occurs when exciton-polaritons undergo resonant Rayleigh scattering. The resulting spin pattern in momentu…
