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…
Exciton-polaritons in CsPbBr crystals revealed by optical reflectivity in high magnetic fields and two-photon spectroscopy
Dmitri R. Yakovlev, Scott A. Crooker, Marina A. Semina +5
Cesium lead bromide (CsPbBr) is a representative material of the emerging class of lead halide perovskite semiconductors that possess remarkable optoelectronic properties. Its…
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…
Optical harmonic generation on the exciton-polariton in ZnSe
Johannes Mund, Dmitri R. Yakovlev, Marina A. Semina +1
We study optical harmonic generation on the 1S exciton-polariton in the semiconductor ZnSe. Intense and spectrally narrow exciton resonances are found in optical second (SHG), thir…
Magneto-toroidal nonreciprocity of second harmonic generation
J. Mund, D. R. Yakovlev, A. N. Poddubny +3
The Lorentz reciprocity principle is a fundamental concept that governs light propagation in any optically linear medium in zero magnetic field. Here, we demonstrate experimentally…
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…
Third harmonic generation on exciton-polaritons in bulk semiconductors subject to a magnetic field
W. Warkentin, J. Mund, D. R. Yakovlev +7
We report on a comprehensive experimental and theoretical study of optical third harmonic generation (THG) on the exciton-polariton resonances in the zinc-blende semiconductors GaA…
High-Resolution Second Harmonic Generation Spectroscopy with Femtosecond Laser Pulses on Excitons in CuO
Johannes Mund, Dietmar Fröhlich, Dmitri R. Yakovlev +1
We present a novel spectroscopic technique for second harmonic generation (SHG) using femtosecond laser pulses at 30~kHz repetition rate, which nevertheless provides high spectral…
Exciton spectroscopy of semiconductors by the method of optical harmonics generation
D. R. Yakovlev, V. V. Pavlov, A. V. Rodina +4
Nonlinear optical phenomena are widely used for the study of semiconductor materials. The paper presents an overview of experimental and theoretical studies of excitons by the meth…
