Vertical Engineering for Large Brillouin Gain in Unreleased Silicon-Based Waveguides

L. Mercadé, A.V. Korovin, Yan Pennec, J. Ahopelto, Bahram Djafari-Rouhani, A. Martínez

Strong acousto-optic interaction in high-index waveguides and cavities generally requires the releasing of the high-index core to avoid mechanical leakage into the underlying low-index substrate. This complicates fabrication, limits thermalization, reduces the mechanical robustness, and hinders…

Theoretical analysis of the effect of the interfacial MoSe$_2$ layer in CIGS-based solar cells

Adama Sylla, N’guessan Armel Ignace, Touré Siaka, Jean-Pierre Vilcot

The aim of this work is to analyze the influence of the interfacial MoSe$_2$ layer on the performance of a /n-ZnO/i-ZnO/n-Zn(O,S)/p-CIGS/p⁺-MoSe₂/Mo/SLG solar cell. In this investigation, the numerical simulation software AFORS-HET is used to calculate…

23 - Multilayered Structures Based One Dimensional Photonic Crystals for MEMS Applications

Cécile Ghouila-Houri, Abdelkrim Talbi, Abdellatif Akjouj, El Houssaine El Boudouti, Bahram Djafari-Rouhani, L. Dobrzynski

This chapter presents and discusses the modeling of multilayered structures based 1D photonic crystals for micro-electro-mechanical systems (MEMS) applications. We particularly report in this chapter a design for realizing a 1D photonic crystal cavity based on highly flexible thin elastomer that…

Topological surface wave metamaterials for robust vibration attenuation and energy harvesting

Xinyue Wu, Yabin Jin, Abdelkrim Khelif, Xiaoying Zhuang, Timon Rabczuk, Bahram Djafari-Rouhani

We propose topological metamaterials working in Hertz frequency range, constituted of concrete pillars on the soil ground in a honeycomb lattice. Based on the analog of the quantum valley Hall effect, a non-trivial bandgap is formed by breaking the inversion symmetry of the unit cell. A topological…

10 - Photonic Demultiplexers Based on Fano and Induced Transparency Resonances

El Houssaine El Boudouti, Abdellatif Akjouj, Bahram Djafari-Rouhani, Abdelkrim Talbi, L. Dobrzynski

In this chapter, we give an analytical and experimental demonstration of the possibility to realize a simple photonic demultiplexer based on Fano and electromagnetically induced transparency resonances. The demultiplexer consists on a Y-shaped waveguide with an input line and two output lines. Each…

12 - Serial Loop Structures: Photonic Bandgaps, Confined, Cavity, and Surface Modes

El Houssaine El Boudouti, Bahram Djafari-Rouhani, Abdellatif Akjouj, L. Dobrzynski

In this chapter, we investigate the electromagnetic band structure, transmission, phase time, as well as confined and surface modes in a one-dimensional photonic structure made of loops pasted together with segments of finite length. In this serial loop structure, the loops and segments are…

Efficient combinations of NOMA with distributed antenna systems based on channel measurements for mitigating jamming attacks

Joumana Farah, Eric Pierre Simon, Pierre Laly, Gauthier Delbarre

This study aims at proposing new efficient combinations of distributed antenna systems (DAS) with non orthogonal multiple access (NOMA) for combating the influence of harmful jamming on a downlink transmission system. A large set of practical channel measurements was performed in an indoor work…

Double-side effect of B/C ratio on BDD electrode detection for heavy metal ion in water

J. Pei, X. Yu, S. Wei, Rabah Boukherroub, Y. Zhang

BDD (Boron-doped Diamond) electrode may hold a promising application to detect heavy metal ions for actual water monitoring and early warning, but a poor understanding of influence mechanism of B/C ratio on detection performance is in the way of its fabrication and application. This work is…
