Band gap engineering in simultaneous phononic and photonic crystal slabs

Bahram Djafari-Rouhani, Yan Pennec, El Houssaine El Boudouti, Jerome O. Vasseur, Youssef El Hassouani, C. Li, Abdellatif Akjouj, Driss Bria

We discuss the simultaneous existence of phononic and photonic band gaps in two types of phononic crystals slabs, namely periodic arrays of nanoholes in a Si membrane and of Si nanodots on a SiO2 membrane. In the former geometry, we investigate in detail both the boron nitride lattice and the…

Subterahertz hypersound attenuation in silica glass studied via picosecond acoustics

Simon Ayrinhac, Marie Foret, Arnaud Devos, Benoit Ruffle, Eric Courtens, René Vacher

We report picosecond acoustic measurements in silica-glass films grown by wet thermal oxidation on a (111) silicon substrate. The longitudinal acoustic phonons are observed over the range from 150 to 300 GHz using an infrared pump and a second harmonic blue probe. The transducer is an aluminum thin…
