Polymer based flapping-wing robotic insect : progress in design, fabrication and characterization

Alexandre Bontemps, Thomas Vanneste, Caroline Soyer, Jean-Bernard Paquet, Sébastien Grondel, Eric Cattan

In the last decade, many researchers pursued the development of tiny flying robots inspired by natural flyers destined for the exploration of confined spaces, for example. Within this context, our main objective is to devise a flying robot bioinspired from insect in terms of size and wing…

[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…

Surface acoustic wave bandgaps for conical pillars on a piezoelectric substrate

Abdelali Mrabti, Mourad Oudich, Abdellatif Akjouj, Yan Pennec, Bahram Djafari-Rouhani, Abdelkrim Talbi, Jérémy Streque, Yu Du, Ali Soltani, Philippe Pernod

We report theoretically on the band structure of a square lattice phononic crystal made up of nickel (Ni) conical pillars deposited on the surface of a semi-infinite LiNbO3 substrate. Calculations have been performed with a 3D finite element method taking into account material anisotropy and…

Key parameters of silicon micropillar arrays for solar cell performance optimization

Di Zhou, Yan Pennec, Bahram Djafari-Rouhani, Odile Cristini, Tao Xu, Yannick Lambert, Didier Stiévenard

Surface nanostructuration is an important challenge for the optimization of light trapping design in solar cell. We present simulations of the optical properties and efficiency of nanostructured (micropilars-MPs- or nanocones-NCs-) silicon based solar cells as well as measurements of their optical…

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-…

Modeling light-sound interaction in nanoscale cavities and waveguides

Yan Pennec, Vincent Laude, Nikos Papanikolaou, Bahram Djafari-Rouhani, Mourad Oudich, Said El-Jallal, Jean-Charles Beugnot, José Maria Escalante, Alejandro Martinez

The interaction of light and sound waves at the micro and nanoscale has attracted considerable interest in recent years. The main reason is that this interaction is responsible for a wide variety of intriguing physical phenomena, ranging from the laser-induced cooling of a micromechanical resonator…

0.2-μm InP/GaAsSb DHBT power performance with 10 mW/μm² and 25% PAE at 94 GHz

Mohammed Zaknoune, Etienne Okada, Estelle Mairiaux, Yannick Roelens, Damien Ducatteau, Peter Frijlink, Marc Rocchi, Hassan Maher

We report a 94-GHz large-signal load-pull characterization of InP/GaAsSb double heterojunction bipolar transistors. The investigated devices have an emitter area of 0.20 × 9.5 μm2. Biased for highest power added efficiency (PAE), an output power of 6.62 mW/μm2 (11 dBm), a power gain of 5.2 dB, and…
