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...

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...

[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....

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.

Event-driven ECG classification using an open-source, LC-ADC based non-uniformly sampled dataset

M. Saeed, Q. Wang, O. Märtens, Benoit Larras, Antoine Frappé, B. Cardiff, D. John

In this article, non-uniformly sampled electrocardiogram (ECG) signals obtained from level-crossing analog-to-digital converters (LC-ADCs) are analyzed for event-driven classification and compression performance. The signal compression results show that it is important to assess the distortion in...
