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...

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...

18 - Optical Tamm States in Semiinfinite Layered Photonic Crystals

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

We investigate localized and resonant optical waves associated with a semiinfinite one-dimensional photonic crystal constructed by two different layers (1 and 2) and terminated with a cap layer. In this chapter, we present an analytic determination of the response function (Green's function)...

Equivalence between angular spectrum-based and multipole expansion-based formulas of the acoustic radiation force and torque

Zhixiong Gong, Michael Baudoin

Two main methods have been proposed to derive the acoustical radiation force and torque applied by an arbitrary acoustic field on a particle: The first one relies on the plane wave angular spectrum decomposition of the incident field (see Sapozhnikov and Bailey [J. Acoust. Soc. Am. 133, 661-676 (...

Electronic-components less fully textile multiple resonant combiners for body-centric near field communication

Baptiste Garnier, Philippe Mariage, François Rault, Cédric Cochrane, Vladan Koncar

Smart and e-textiles have nowadays an important increasing place in the garment industry. The rise of embedded telecommunications, especially smartphones in our pocket, enables us to provide a power source and a wireless link for smart textiles. The main issue is to develop garments able to receive...

Graphene-Coated Gold Chips for Enhanced Goos–Hanchen Shift Plasmonic Sensing

C.M. Das, L. Kang, D. Hu, Y. Guang, Y. Guo, M. Wei Chen, P. Coquet, K.-T. Yong

Plasmon-based sensing relies on the interaction of photons with nanostructured materials. Surface plasmon resonance (SPR) biological and chemical sensors offer unique advantages of real-time and label-free detection techniques and therefore, they have been around in the commercial market for many...

Enhancement of both optical and catalytic activity of copper-decorated porous silicon micro-particles

Abderrahmane Hamdi, Chohdi Amri, Rachid Ouertani, El Hadj Dogheche, Hatem Ezzaouia

To the best of our knowledge, this study is the first to investigate the effect of chemical vapour etching (CVE) combined with copper decoration on both the optical and catalytic activities of silicon micro-particles (SiμPs). After exposure to acid vapours emanating from a hot solution of hydrogen...

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...

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...
