Coherent control of optical phonons in GaAs was achieved by using phased-locked paired femtosecond pulses on an n-GaAs(001) sample. The results suggest that the diagonal components of the Raman tensor play a critical role in the generation of coherent longitudinal optical phonons, contrasting previous experiments using parallel-polarized pulses.
Coherent control of the optical phonons in GaAs is realized via paired femtosecond pulses that are relative phase locked and have perpendicular polarizations. To investigate polarization effects, only phonon interference occurs, which contrasts previous experiments with parallel-polarized pulses, which produced as well electronic interference. The results suggest that for an n-GaAs(001) sample the diagonal components of the Raman tensor determinate in the generation of coherent longitudinal optical phonons.
