Dynamic visualization of surface phonons in phononic crystals
2011Using ultrashort pulsed optical excitation and interferometric detection, we dynamically image ultrahigh-frequency surface acoustic phonon wavepackets on two-dimensional (2D) phononic crystals. The samples consist of a square lattice of air-filled holes etched in a silicon substrate. Good agreement is found when compared with time-domain finite element
