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…
