2 - Closed loop

L. Dobrzynski, Housni Al Wahsh, Abdellatif Akjouj, El Houssaine El Boudouti, Cécile Ghouila-Houri, Abdelkrim Talbi, Gaëtan Lévêque, Bahram Djafari-Rouhani

A closed loop can be obtained by linear superposition of the two free ends of an open loop. Its main property is the double degeneracy of its states. The analytical expressions of its eigenvalues, eigenfunctions, and response function are presented. The case of two simultaneous identical measures...

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...
