Magnonic analogue of electromagnetic induced transparency in detuned magnetic circuit

Abdelkader Mouadili, El Houssaine El Boudouti, Housni Al-Wahsh, Abdellatif Akjouj, Bahram Djafari-Rouhani, L. Dobrzynski

A simple magnetic device consisting of two dangling side stubs grafted at the same site along a waveguide is designed to obtain a magnonic analogue of electromagnetic induced transparency (EIT) resonance. By detuning the lengths of the two stubs, a resonance can be squeezed between two transmission…

Surface acoustic waves in one-dimensional piezoelectric-metallic phononic crystal: Effect of a cap layer

M. Alami, E. H. El Boudouti, Bahram Djafari-Rouhani, Y. El Hassouani, Abdelkrim Talbi

We study the propagation of transverse acoustic waves associated with the surface of a semi-infinite superlattice (SL) composed of piezoelectric-metallic layers and capped with a piezoelectric layer. We present closed-form expressions for localized surface waves, the so-called Bleustein-Gulyaev (BG…

Thin-film adhesion characterization by Colored Picosecond Acoustics

Arnaud Devos, P. Emery

This paper presents some applications of a recent technique so-called the Colored Picosecond Acoustics (APiC) to the characterization of complex stacks of thin films. The technique is a unique combination of optics and acoustics that implements an acoustic pulse-echo technique at the nanoscale…

Magnetoplasmonic nanograting geometry enables optical nonreciprocity sign control

L. Halagačka, Mathias Vanwolleghem, Francois Vaurette, J. Ben Youssef, K. Postava, J. Pištora, Béatrice Dagens

We experimentally demonstrate a disruptive approach to control magnetooptical nonreciprocal effects. It has been known that the combination of a magneto-optically (MO) active substrate and extraordinary transmission (EOT) effects through deep-subwavelength nanoslits of a noble metal grating, leads…

Chapter 5 - Transmission in 2D phononic crystals and acoustic metamaterials

Yan Pennec, Bahram Djafari-Rouhani, Abdellatif Akjouj, Gaëtan Lévêque, El Houssaine El Boudouti, Housni Al-Wahsh, L. Dobrzynski

In this chapter we describe the basic concepts of two-dimensional (2D) phononic crystals. We start with a detailed presentation of the elementary methods for the calculation of band structures and transmission phenomena which have proven their efficiency in the literature. We respectively present…

A broadband 4-18 GHz active quadrature hybrid

Paul Sangare, Christophe Loyez, Kevin Carpentier, Markus Mayer, Dirk Hartung, Francois Parickmiler, Nathalie Rolland

This paper presents an innovative topology of a broadband active quadrature hybrid. This novel architecture consists of a traveling wave amplifier with a unique coupling mechanism, providing amplitude flatness and low phase imbalance over the 4 - 18 GHz frequency band. Experimental results validate…

Effect of MoS2 layer on the LSPR in periodic nanostructures

Mohamed El Barghouti, Abdellatif Akjouj, Abdellah Mir

Abstract In this work, we propose a new configuration of the localized surface plasmon resonance (LSPR), based on MoS2 hybrid structures for ultrasensitive biosensing applications. The plasmonic resonances are widely used in bimolecular detection and continue to be an active network because of the…

Nano-structured top contact with low optical polarization dependence for THz generation using photodiodes

Sara Bretin, Maximilien Billet, Emilien Peytavit, Francois Vaurette, Christophe Coinon, X. Wallart, Jean-Francois Lampin, Malek Zegaoui, Guillaume Ducournau, Mohammed Zaknoune

Uni-travelling carrier photodiode (UTC-PD) with different top optical and electrical accesses are proposed towards optical polarization sensitivity reduction. With the optimized structure, only 1 percent dependence in optical polarization is obtained while ensuring good RF access. Measurements up…
