Generation and remote detection of THz sound using semiconductor superlattices
M. Trigo, T. A. Eckhause, J. K. Wahlstrand +3
The authors introduce a novel approach to study the propagation of high frequency acoustic phonons in which the generation and detection involves two spatially separated superlatti…

Cherenkov radiation emitted by ultrafast laser pulses and the generation of coherent polaritons
J. K. Wahlstrand, R. Merlin
We report on the generation of coherent phonon polaritons in ZnTe, GaP and LiTaO using ultrafast optical pulses. These polaritons are coupled modes consisting of mostly far-i…
