Phonons in Slow Motion: Dispersion Relations in Ultra-Thin Si Membranes

John Cuffe, Emigdio Chavez, Andrey Shchepetov, Pierre-Olivier Chapuis, El Houssaine El Boudouti, Francesc Alzina, Timothy Kehoe, Jordi Gomis-Bresco, Damian Dudek, Yan Pennec, Bahram Djafari-Rouhani, Mika Prunnila, Jouni Ahopelto, Clivia. M. Sotomayor Torres

We report the changes in dispersion relations of hypersonic acoustic phonons in free-standing silicon membranes as thin as \sim 8 nm. We observe a reduction of the phase and group velocities of the fundamental flexural mode by more than one order of magnitude compared to bulk values. The...

Light modulation in phoxonic nanocavities

Nikos Papanikolaou, I.E. Psarobas, N. Stefanou, Bahram Djafari-Rouhani, Bernard Bonello, Vincent Laude

We report on the occurrence of strong nonlinear acousto-optic interactions in phoxonic structures, that support, simultaneously, acoustic and optical localized resonant modes, under the influence of acoustic losses. Deploying a detailed theoretical investigation of the acousto-optic coupling in the...

Phononic and photonic properties of a stubbed strip waveguide

Yan Pennec, Bahram Djafari-Rouhani, Mourad Oudich, Said El-Jallal, Josemaria Escala, Alejandro Martinez, Vincent Laude

Many studies have been devoted to the search of photonic and phononic band gaps, but relatively few works are dealing with the simultaneous control of phonons and photons. Phoxonic structures hold promises for the simultaneous confinement and tailoring of sound and light waves with potential...
