Fabrication and characterization of 2D phononic crystals based on lithium niobate substrate and nickel pillars

Yu Du, Abdelkrim Talbi, Jean-Claude Gerbedoen, Sergey Yankin, Philippe Pernod, Vladimir Preobrazhensky, Olivier Bou Matar

This work presents experimental investigation of interaction between surface acoustic waves and 2D surface Phononic crystals (PnCs). The PnC is made of 2D array of resonant nickel pillars arranged in different symmetric lattices, and deposited on lithium niobate (Y128 cut) substrate. Measurement of…

A fast and functional technique for the noise figure measurement of differential amplifiers

Yogadissen Andee, Jérôme Prouvée, François Graux, Francois Danneville

This paper presents an original technique to measure the noise figure of differential amplifiers with a four-port network analyzer. The approach is fast and simple as the S-parameters and the output noise powers are measured directly with the analyzer. There is no need of hybrid couplers or baluns…

[Invited] A phoxonic crystal : photonic and phononic bandgaps in a 1D optomechanical crystal

Jordi Gomis-Bresco, Daniel Navarro-Urrios, Mourad Oudich, Said El-Jallal, Amadeu Griol, Daniel Puerto, Emigdio Chavez, Yan Pennec, Bahram Djafari-Rouhani, Francesc Alzina, Alejandro Martínez, C.M. Sotomayor Torres

Recent years have witnessed the increase of interest in cavity optomechanics, which exploits the confinement and coupling of optical waves and mechanical vibrations at the nanoscale. Amongst the different physical implementations, optomechanical (OM) crystals built on semiconductor slabs would…

Comparison of shallow-mesa InAs/AlSb HEMTs with and without early-protection for long-term stability against Al(Ga)Sb oxidation

E. Lefebvre, G. Moschetti, M. Malmkvist, L. Desplanque, X. Wallart, J. Grahn

The fabrication process of InAs/AlSb high electron mobility transistors (HEMTs) has been improved by depositing, after the shallow-mesa isolation of the active area, a thin SiNx-film on the exposed AlGaSb mesa floor. Devices with and without this early-protection against Al(Ga)Sb oxidation have…

Longitudinal and transversal polarization switching in strained ferroelectrics

Laurent Baudry, Igor A. Luk'Yanchuk, A. Razumnaya

Using the multicomponent Landau-Devonshire functional we study the field-induced polarization switching in c-oriented ferroelectric phase of epitaxial perovskite film and found that two different regimes are possible: (i) longitudinal switching with change of the polarization modulus and (ii)…

Multiuser phase coded costas signals with improved cross-correlation and partial cross-ambiguity properties

Nadjah Touati, Charles Tatkeu, Atika Rivenq, Thierry Chonavel

Costas codes are a variant of frequency hopping codes that achieve the «thumbtack» auto-ambiguity function needed in radar applications. However, they may show poor cross- ambiguity properties when selected and assigned randomly which makes them poorly adapted to multiuser radar applications. In…

Noise performance of frequency modulation Kelvin force microscopy

Heinrich Diesinger, D. Deresmes, Thierry Melin

Noise performance of a phase-locked loop (PLL) based frequency modulation Kelvin force microscope (FM-KFM) is assessed. Noise propagation is modeled step by step throughout the setup using both exact closed loop noise gains and an approximation known as "noise gain" from operational…

Sensing light and sound velocities of fluids in 2D phoxonic crystal slab

Yan Pennec, R. Moiseyenko, Bahram Djafari-Rouhani, S. Amoudache, R. Tigrine, R. Lucklum, A. Khater

We study theoretically the potentiality of dual phononic-photonic (the so-called phoxonic) crystals for sensing applications. In this work, we study the transmission normal to a periodically perforated silicon slab when the surrounding medium is a liquid. We investigate the existence of well-…

Fabrication of superhydrophobic and highly oleophobic silicon-based surfaces via electroless etching method

Thi Phuong Nhung Nguyen, Renaud Dufour, Vincent Thomy, Vincent Senez, Rabah Boukherroub, Yannick Coffinier

This study reports on a simple method for the preparation of superhydrophobic and highly oleophobic nanostructured silicon surfaces. The technique relies on metal-assisted electroless etching of silicon in sodium tetrafluoroborate (NaBF4) aqueous solution. Then, silver particles were deposited on…
