A Comparative Study of Asynchronous and Synchronous OCDMA Systems

Hichem Mrabet, Abdelhamid Cherifi, Thiago Raddo, Iyad Dayoub, Shyqyri Haxha

This article presents a detailed survey on both asynchronous and synchronous Optical Code-Division Multiple-Access (OCDMA) systems based on 1-D, 2-D, and 3-D codes, distinctively. Accordingly, different coding schemes along with their multiplexing capacity, correlation features, advantages and…

Ultrafast strain waves reconstruction from coherent acoustic phonons reflection

Kwan To Lai, Daniel Finkelstein-Shapiro, Arnaud Devos, Pierre-Adrien Mante

Picosecond ultrasonics, which studies laser-induced high-frequency strain waves, is a reliable and versatile method for nondestructive materials' characterization. Strain waves are generated through a light interaction with charges and their subsequent relaxation, and these waves conceal a…

Polarization control of emitted THz waves using spintronic emitters with anisotropic magnetic layers & birefringence characterization of Quartz

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

We demonstrate that 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. The…

Beyond the Dynamic range approach In noise evaluation for Terahertz Time domain spectrometers

Clemence Muller, Melanie Lavancier, Jeyan Bichon, Theo Hannotte, Jean-Francois Lampin, Sophie Eliet, Romain Peretti

THz-TDS is used for a myriad of purposes. Still today, the usual way to compare different system in terms of signal to noise ratio is to look at the dynamic range. We propose here a more reliable method based on statistics and will show results on two systems (Toptica and Menlo).

THz s-SNOM imaging of logarithmic spiral antennas

C. Santos, Louis Thomas, Théo Hannotte, Melanie Lavancier, Sophie Eliet, Jean-Francois Lampin, Romain Peretti

Probing the near-field of photonic components at sub-wavelength scale is of high interest to improve the design of future THz devices. We report on the THz near-field imaging of logarithmic spiral antennas by scattering-type scanning near-field optical microscopy (s-SNOM). Our results demonstrate…

A criterion to compare permittivity models in the terahertz range

Melanie Lavancier, Nabil Vindas Yassine, Juliette Vlieghe, Jean-Francois Lampin, Romain Peretti

We present a method to take experimental noise in THz-TDS into account during the fitting process. With its implementation in our software fit@TDS, we were able to fit accurately the spectrum of the golden sample: a lactose pellet.

SiGe Based LNA for Data Communication Applications at 211 GHz

Haitham Ghanem, Sylvie Lepilliet, Daniel Gloria, Francois Danneville, Guillaume Ducournau

We report the use of a silicon based 211 GHz preamplifier for THz links. A test bench setup is assembled to evaluate the performance of the amplifier using a uni-traveling-carrier photodiode (UTC-PD) as the source of a 5Gbps modulated signal. The Bit Error Rate curve was extracted versus the input…

Magneto-electric control of polarization in spintronic terahertz emitters

Nicolas Tiercelin, Geoffrey Lezier, Pierre Kolejak, Jean-Francois Lampin, Yannick Dusch, Kamil Postava, Mathias Vanwolleghem

Magnetoelectric control of the emitted polarization of THz waves was demonstrated for the first time in spintronic emitters thanks to the use of a magnetostrictive ferromagnetic layer in an emitter deposited on top of a ferroelectric relaxor substrate.

Complex refractive indices in the TeraHertz domain of samples from atmospheric aerosol sources

Jeyan Bichon, Melanie Lavancier, Denis Petitprez, Alexandre Deguine, D. Hourlier-Bahloul, Karine Deboudt, Hervé Herbin, Guillaume Ducournau, Romain Peretti, Sophie Eliet

We report the TeraHertz (THz) characterization of calcium carbonate (CaCO3) particles, one of the major components of desert dust, to determine the real and imaginary parts of their complex refractive indices. The optical characterization is done by TeraHertz Time Domain Spectroscopy (THz-TDS)…
