20 - Omnidirectional Bandgaps and Selective Transmission in Layered Photonic Crystals

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

It has been shown that a one-dimensional periodic structure such as a layered photonic crystal can exhibit the property of omnidirectional reflection, which means that any incident wave launched from the vacuum (or from a substrate) will undergo a total reflection at the layered photonic crystal…

Large-area femtosecond laser milling of silicon employing trench analysis

Arun Bhaskar, Justine Philippe, Flavie Braud, Etienne Okada, Vanessa Avramovic, Jean-François Robillard, Cédric Durand, Daniel Gloria, Christophe Gaquière, Emmanuel Dubois

A femtosecond laser is a powerful tool for micromachining of silicon. In this work, large-area laser ablation of crystalline silicon is comprehensively studied using a laser source of pulse width 300 fs at two wavelengths of 343 nm and 1030 nm. We develop a unique approach to gain insight into the…

Coherent polarization rotation of TeraHertz spintronic emitters with in-plane uni-axial magnetic anisotropy

Geoffrey Lezier, Pierre Koleják, Jean-Francois Lampin, Kamil Postava, Mathias Vanwolleghem, Nicolas Tiercelin

Spintronic TeraHertz emitters using uni-axial anisotropic FeCo/TbCo 2 /FeCo ferromagnetic layers allow the polarization control of the THz emitted wave thanks to the Stoner-Wohlfarth coherent rotation of magnetization when submitted to a magnetic field along hard axis.

Alpha-stable model for interference in IoT networks

Laurent Clavier, Troels Pedersen, Ignacio Rodriguez Larrad, Malcolm Egan

The increase in connected device, linked with the evolution of IoT and cellular networks with 5G and towards 6G makes crucial the limitation of the interference impact. Devices in networks (like LoRa, SigFox and even WiFi) or in different networks are not necessarily coordinated to optimize their…
