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…
Interaction between Rydberg Excitons in Cuprous Oxide Revealed through Second Harmonic Generation
Dirk Semkat, Heinrich 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…
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…
Efficient launch of shear phonons in photostrictive halide perovskites
Dmytro Horiachyi, Mikhail O. Nestoklon, Ilya A. Akimov +10
Optical generation of transverse coherent phonons by femtosecond light pulses is appealing for high-speed sub-THz active control of material properties. Lead-free double perovskite…
