Using Fourier-transform spectral interferometry, we demonstrate the measurement of both amplitude and phase of photon echoes in GaAs multiple-quantum-well structures. The complete measurement of the electric field thus achieved makes possible the determination of the corresponding Wigner spectrograms.

We demonstrate a technique of photon-echo interferometry which provides extraordinary sensitivity for the measurement of the relative phase in the coherences for pairs of optical transitions. The method is applied to study collision-induced optical-coherence transfer between adjacent transitions in atomic samarium vapor.
