Interaction between Rydberg Excitons in Cuprous Oxide Revealed through Resonant Second Harmonic Generation
Andreas Farenbruch, Henje Stolz, Peter Grünwald +5
We report experimental and theoretical investigations of interacting excitons of the yellow series in cuprous oxide (CuO) with principal quantum numbers up to by means of secon…
Polarization- and time-resolved nonlinear multi-photon spectroscopy for confocal microscopy of semiconductor nanostructures
Nikita V. Siverin, Andreas Farenbruch, Dmitri R. Yakovlev +4
We present a versatile confocal microscopy setup for optical second harmonic generation (SHG) and multi-photon spectroscopy that enables polarization-resolved studies of semiconduc…
Coherence of dipole-forbidden Rydberg excitons in CuO measured by polarization- and time-resolved multi-photon spectroscopy
A. Farenbruch, N. V. Siverin, G. Uca +3
Quantum applications of solid state systems base upon generation and control of coherent electronic excitations. Prominent examples are exciton states in semiconductors excitable b…

Nonreciprocal magnetic-field-induced second harmonic generation of exciton polaritons in ZnSe
J. Mund, D. R. Yakovlev, A. Farenbruch +5
We report on the optical second harmonic generation (SHG) on the 1S exciton-polariton resonance in bulk ZnSe that is subject to an external magnetic field applied perpendicular to…
Exchange interaction in the yellow exciton series of cuprous oxide
Patric Rommel, Jörg Main, Andreas Farenbruch +2
We experimentally and numerically investigate the exchange interaction of the yellow excitons in cuprous oxide. By varying the material parameters in the numerical calculations, we…
Optical second and third harmonic generation on excitons in ZnSe/BeTe quantum wells
Johannes Mund, Andreas Farenbruch, Dmitri R. Yakovlev +3
Optical harmonic generation on excitons is found in ZnSe/BeTe quantum wells with type-II band alignment. Two experimental approaches with spectrally-broad femtosecond laser pulses…
Second Harmonic Generation of cuprous oxide in magnetic fields
Patric Rommel, Jörg Main, Andreas Farenbruch +5
Recently Second Harmonic Generation (SHG) for the yellow exciton series in cuprous oxide has been demonstrated [J. Mund et al., Phys. Rev. B 98, 085203 (2018)]. Assuming perfect $O…
Magneto-Stark and Zeeman effect as origin of second harmonic generation of excitons in CuO
A. Farenbruch, J. Mund, D. Fröhlich +4
We report on the experimental and theoretical investigation of magnetic-field-induced second harmonic generation (SHG) and two-photon absorption (TPA) of excited exciton states ($n…
