Abstract
Polarization-dependent heterodyne four-wave-mixing measurements with a phase-conjugate Michelson interferometer reveal a macroscopic nonradiative 770-THz oscillation in the nonlinear optical susceptibility of GaAs multiple quantum wells. The oscillation is interpreted as the temporal evolution of the two-photon nonradiative biexcitonic coherence.
