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…

Terahertz sensing of supercooled glycerol using a 1D photonic crystal

Juraj Sibik, Hynek Nemec, Christelle Kadlec, Filip Kadlec, Vladimir Skoromets, Karine Blary, J. Axel Zeitler, Petr Kužel

We have developed a 1D photonic crystal that can be used for sensing purposes at terahertz frequencies and which requires less then one microliter of sample material. Using this sensor we have obtained temperature dependent measurements of refractive index and extinction coefficient of glycerol in…

[Invited] Localized phoxonic modes and application to sensor devices

Yan Pennec, Samira Amoudache, Bahram Djafari-Rouhani

Photonic crystals and their acoustic counterpart, the so-called phononic crystals are now well-known for their ability to guide, control, and manipulate the propagation of the optic and acoustic waves. These properties are mainly related to the possibility of band gaps in their band structure that…

Reducing crosstalk in array structures by controlling the excitation voltage of individual elements : a feasibility study

Abdelmajid Bybi, Sébastien Grondel, Jamal Assaad, Anne-Christine Hladky, Christian Granger, Mohamed Rguiti

This paper describes a procedure to minimize crosstalk between the individual elements of a piezoelectric transducer array. A two-dimensional finite elements model was developed and the excitation voltages predicted by the model were applied to the array prototypes made of PZT 27 ceramic. Symmetric…

Three-Paths Microwave Inteferometric System Based on a Six-Port technique

Kamel Haddadi, Tuami Lasri

This paper presents a new type of six-port instrument to meet the specific needs of electrical characterization tools for impedances clearly different than the standard 50 Omega reference impedance. A method is developed for the precise adjustment of the reference impedance of the measurement…
