Paper Abstract

Room temperature bulk GaAs and GaAs/A1GaAs multiple quantum well (MQW) samples are studied using backward degenerate four wave mixing (DFWM) at moderately high pump intensities (4 kW/cm2). The DFWM reflectivity is measured in the band gap region as a function of laser wavelength and pump intensity. When the MQW is pumped at intensities sufficient to saturate the excitonic resonance, a dispersive DFWM spectrum consistent with conduction band contributions is observed. Preliminary experiments in bulk GaAs indicate that the phase conjugate signal strength is the same as that for the MQW at approximately the same pump intensity.
