title: Orientational dependence of degenerate four-wave mixing in multiple-quantum-well structures.
abstract: The transient grating technique is used to demonstrate how the temporal response of four-wave mixing in multiple-quantum-well structures depends on sample orientation. Variation of the decay times associated with the short-period grating in a phase-conjugate geometry between 40 and 500 psec is demonstrated in a GaAs/AlGaAs multiple-quantum-well structure and interpreted in terms of the large anisotropy in the carrier diffusion.
