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…
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…
Polar phonons and magnetic excitations in the antiferromagnet CoF
R. M. Dubrovin, A. Tellez-Mora, A. C. Garcia-Castro +6
The coupling between antiferromagnetic spins and infrared-active phonons in solids is responsible for many intriguing phenomena and is a field of intense research with extensive po…
