Linear combining in dependent α-stable interference

Ce Zheng, Malcolm Egan, Laurent Clavier, Troels Pedersen, Jean-Marie Gorce

Recently, there has been a proliferation of wireless communication technologies in unlicensed bands for the Internet of Things. A key question is whether these networks can coexist given that they have different power levels, symbol periods, and access protocols. The main challenge is to...

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...

[Invited] SOI-based opto-mechanical Terahertz bolometer operating at room temperature with microsecond response time

K. Froberger, Marc Faucher, B. Walter, M. Lavancier, Romain Peretti, Jean-Francois Lampin, Guillaume Ducournau, S Barbieri

We report the operation of a Terahertz (THz) detector exploiting the bi-material effect to resonantly excite a cantilever (CL) of micrometric size. The detector is fabricated on a SOI substrate and coupling to the incident THz radiation is obtained using two coupled aluminum half-dipole antennas....

15 - Silicon Nanowires and Nanopillars for Photovoltaic

Yan Pennec, Abdellatif Akjouj, Gaëtan Lévêque, Bahram Djafari-Rouhani, L. Dobrzynski

We present simulations on both the optical properties and the efficiency of nanowires (NWs), nanopillars (NPs) and nanocones (NCs) silicon-based solar cells, together with measurements on their associated optical absorption. We address the calculation using Green's function formalism and...

Experimental Evidence of the Existence of Bound States in the Continuum and Fano Resonances in Solid-Liquid Layered Media

Madiha Amrani, Ilyasse Quotane, Cécile Ghouila-Houri, El Houssaine El Boudouti, Leonid Krutyansky, Bogdan Piwakowski, Philippe Pernod, Abdelkrim Talbi, Bahram Djafari-Rouhani

Bound states in continuum (BICs) are resonances with zero width (infinite lifetime) without any leakage into the surrounding media. Their fascinating properties and potential applications have attracted a great deal of interest. In this paper, we give an analytical, numerical, and experimental...

16 - Transmission Line Photonic Crystals: A Comparison of Green's Formalism, Lumped Circuit Element Model, and Finite Element Method

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

This chapter presents the modeling, using Advanced Design System (ADS) from Keysight Technologies and Finite Element Method (FEM) based on Comsol Multiphysics tools, of photonic circuits. We particularly report in this chapter a confirmation of the results reported in Chapters 9, 10, and 11...
