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…

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…
