Lifetimes of Confined Acoustic Phonons in Ultra-Thin Silicon Membranes

John Cuffe, Emigdio Chávez, Pierre-Olivier Chapuis, Francesc Alzina, Oliver Ristow, Andrey Shchepetov, Mike Hettich, Thomas Dekorsy, Clivia M. Sotomayor Torres, Mika Prunnila, Jouni Ahopelto

We study the relaxation of coherent acoustic phonon modes with frequencies up to 500 GHz in ultra-thin free-standing silicon membranes. Using an ultrafast pump-probe technique of asynchronous optical sampling, we observe that the decay time of the first-order dilatational mode decreases…

Evaluation of damages induced by Ga<su>+</sup> - focused ion beam in piezoelectric nanostructures

A. Ferri, Denis Remiens, R. Desfeux, A. da Costa, D. Deresmes, David Troadec

The impact of Ga+-focused ion beam (FIB) about functional properties of continuous and nanostructured piezoelectric thin films of lead zirconate titanate (Pb(ZrxTi1-x)O3) was investigated. A suitable way to fabricate piezoelectric nanocapacitors was studied, based on the amorphous or crystallized…

Metamaterial-inspired bandpass filters for terahertz surface waves on Goubau lines

Ali K. Horestani, Withawat Withayachumnankul, Abdallah Chahadih, Abbas Ghaddar, Mokhtar Zehar, Derek Abbott, Christophe Fumeaux, Tahsin Akalin

This paper is focused on the application of split ring resonators (SRRs) to the design of compact bandpass filters for terahertz surface waves on single-wire waveguides, the so-called planar Goubau lines (PGLs). Through equivalent circuit models, electromagnetic simulations, and experiments, it is…

A novel inkjet-printed chipless RFID-based passive fluid sensor platform

Sangkil Kim, James Cooper, Manos M. Tentzeris, Robert Herre, Sijia Gu, Tuami Lasri

In this paper, we present a novel chipless RFID-based passive fluid sensor platform which enables a reliable remote fluid identification. The proposed sensor platform consists of a capacitive gap-loaded tunable filter for fluid sensing and two broadband perpendicularly polarized microstrip monopole…

Acousto-optic wide band optical low frequency shifter

Anthony Dieulangard, Jean-Claude Kastelik, Samuel Dupont, Joseph Gazalet

A wide bandwidth tunable optical low-frequency shifter is presented in this work. It is based on two acousto-optic devices operating in tandem. The relevant parameters of the specific configurations of acousto-optic interactions in paratellurite material are detailed. Results from numerical…
