Recent results on femtosecond time‐integrated and time‐resolved four‐wave‐mixing experiments in intrinsic and modulation‐doped GaAs quantum wells are reported. A variety of new phenomena ranging from giant excitonic resonance for intrinsic samples, Fermi liquid behavior in modulation‐doped samples, and interesting temporal evolutions provide new insights into the physical process responsible for the coherent signals.
