Abstract

We present a comprehensive experimental and theoretical investigation of the polarization selection rules for degenerate-four-wave-mixing (DFWM) and quantum beating of hh and lh transitions in a GaAs QW. Depending on the polarization and temporal sequence of the three pulses simultaneous excitation of the hh and lh transitions generates either quantum beats (QB), no modulation of the signal, or a superposition of QB and polarization interference (PI) effects as proved by spectrally resolved (SR)-DFWM. The experiments were conducted using a novel three pulse DFWM geometry enabling the excitation of specific combinations of contributing states by varying the polarization configuration.
