A barium titanate‐on‐oxide insulator optoelectronics platform

Yu Cao, Siew Li Tan, Eric Jun Hao Cheung, Shawn Yohanes Siew, Changjian Li, Yan Liu, Chi Sin Tang, Manohar Lal, Guanyu Chen, Karim Dogheche, Ping Yang, Steven Pennycook, Andrew Thye Shen Wee, Soojin Chua, El Hadj Dogheche, Thirumalai Venkatesan, Aaron Danner

Electro-optic modulators are among the most important building blocks in optical communication networks. Lithium niobate, for example, has traditionally been widely used to fabricate high-speed optical modulators due to its large Pockels effect. Another material, barium titanate, nominally has a 50…

75 nm gate length PHEMT with f max = 800 GHz using asymmetric gate recess: RF and noise investigation

M. Samnouni, Nicolas Wichmann, X. Wallart, Christophe Coinon, Sylvie Lepilliet, S. Bollaert

We report a high maximum frequency of oscillation (f max) and a current-gain cutoff frequency (f T) of 800 and 260 GHz, respectively, with pseudomorphic high-electron mobility transistor (PHEMT), using an InGaAs/InAs composite channel and an asymmetric gate recess. This result was achieved with…

Introduction to IDTC special issue: Joule's bicentenary history of science, foundations and nature of science

Raffaele Pisano, Paulo Mauricio, Philippe Vincent

James Prescott Joule's (1818-1889) bicentenary took place in 2018 and commemorated by the IDTC with a Symposium-'James Joule's Bicentenary: Scientific and Pedagogical Issues Concerning Energy Conservation'-at the European Society for the History of Science (ESHS and BSHS), 14th-…

Composition control of lead‐free piezoelectric BNT thin ceramic films deposited by ex situ sputtering

Ahmad Hamieh, Freddy Ponchel, Denis Remiens

(Bi0.5Na0.5)TiO3 thin film growth by ex situ sputtering has been investigated and reported in this paper. An original approach, based on the growth process, was used in order to precisely control the film composition, which has never been reported in BNT growth. The bismuth content in the films and…

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…

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…

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).
