Continuous-wave lines up to 5.5 THz from the ammonia laser pumped by a quantum cascade laser

Jean-Francois Lampin, M.-H. Mammez, Z. Buchanan, M. Micica, O. Pirali, M.-A. Martin-Drumel, Sophie Eliet, S Barbieri, Francis Hindle, P. Roy, Gaël Mouret

We have recently demonstrated a continuous wave molecular laser emission based on ammonia optically pumped by a quantum cascade laser. We report here new results obtained with an optimized laser prototype pumped by a tunable external cavity quantum cascade laser. New laser lines with high output...

Scaling law, confined and surface modes in photonic fibonacci stub structures: theory and experiment

Hassan Aynaou, Abdelkader Mouadili, Noama Ouchani, El Houssaine El Boudouti, Abdellatif Akjouj, Bahram Djafari-Rouhani

We investigate both theoretically and experimentally the properties of electromagnetic waves propagation and localization in periodic and quasi-periodic stub structures of Fibonacci type. Each block constituting the Fibonacci sequence (FS) is composed of an horizontal segment and a vertical stub....

Serial interference cancellation for improving uplink in LoRa-like networks

Angesom Ataklity Tesfay, Eric Pierre Simon, Guillaume Ferré, Laurent Clavier

In this paper, we present a new receiver design, which significantly improves performance in the Internet of Things networks such as LoRa, i.e., having a chirp spread spectrum modulation. The proposed receiver is able to demodulate multiple users simultaneously transmitted over the same frequency...

Magneto-Electroacoustic Dynamics in a Straintronic Random Access Memory Cell

Vladimir Preobrazhensky, L.M. Krutyansky, Nicolas Tiercelin, Philippe Pernod

The straintronic principle of nonvolatile magnetoelectric random access memory (MELRAM) isattracting attention because of the prospect of achieving ultra-low-power consumption in memory devices onits basis. The mechanism of switching magnetic moments by pulse deformation of elastically coupled mag-...

Development of PZT-based 18 MHz 2D pMUT array with PDMS waveguide

Xu-Bo Wang, Le-Ming He, Wen-Juan Liu, Shu-Ren Song, Wei-Jiang Xu, Qian Cheng, Antoine Riaud, Jun-Yan Ren, Jia Zhou

For high-resolution ultrasonic imaging, an 18 MHz lead zirconate titanate (PZT) based two-dimensional (2D) piezoelectric micromachined ultrasonic transducers (pMUTs) array with polydimethylsiloxane (PDMS) waveguide are developed. The array is composed of 8 x 16 elements with a pitch of 75 mu m and...

Dispersion of IDT-induced high-frequency surface acoustic waves - Application to the mechanical and dimensional characterization of mesoporous silicon

Tahar Kadi, Marc Duquennoy, Katir Ziouche, Mohammadi Ouaftouh, Nikolay Smagin

A method based on the dispersion of surface acoustic waves (SAW) is proposed for the effective characterization of mesoporous silicon (MPS) layers with the possibility of estimating Young's modulus and the thickness of the porous layer, as well as the porosity. For this purpose, IDT were...

Multi-view deep features for robust facial kinship verification

Oualid Laiadi, Abdelmalik Ouamane, Abdelhamid Benakcha, Abdelmalik Taleb-Ahmed, Abdenour Hadid

Automatic kinship verification from facial images is an emerging research topic in machine learning community. In this paper, we proposed an effective facial features extraction model based on multi-view deep features. Thus, we used four pre-trained deep learning models using eight features layers...
