Paper Abstract

Second-harmonic generation (SHG) is studied in semiconductors GaAs and CdTe in broad spectral and temperature ranges. External magnetic field gives rise to time-reversal symmetry breaking causing new optical nonlinearities. A series of narrow SHG lines is observed in the spectral range near the band gap of semiconductors GaAs and CdTe in nonzero magnetic fields. It is found that optical transitions between Landau levels are responsible for observed SHG spectra. The rotational anisotropy of the SHG signal distinctly differs from that of the electric-dipole approximation. Model calculations, based on phenomenological analysis using nonlocal contributions in the nonlinear optical susceptibility, have revealed an importance of the nonlinear magneto-optical spatial-dispersion that comes together with the electric-dipole term.
