Capacity Improvement of 3D-OCDMA-PON Hybrid System Next Generation Using Weight Zero Cross Correlation Code

Abdelhamid Cherifi, Tarik Mohammed Chikouche, Abdullah Karar, Julien Moussa H. Barakat, Omar Arbouche, Iyad Dayoub

This paper proposes a novel code for optical code division multiple access (OCDMA) systems, called the three-dimensional (3D) spectral/temporal/spatial single weight zero cross-correlation (3D-SWZCC) code. The proposed code could potentially be used in the next generation of passive optical…

Ultrafast Modulation of Polarization in Spintronic THz Emitters Enhanced by Field Induced Spin Reorientation Transition

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

We demonstrate an efficient and simple modulation of the polarization in Spin-tronic Terahertz Emitters, by rapid switching of the magnetization using high-frequency magnetic field, enhanced by field induced Spin Reorientation Transition (SRT). The instability of the magnetic layer at the…

Nanomechanical damping via electron-assisted relaxation of two-level systems

Olivier Maillet, Dylan Cattiaux, Xin Zhou, Rasul R. Gazizulin, Olivier Bourgeois, Andrew D. Fefferman, Eddy Collin

We report on measurements of dissipation and frequency noise at millikelvin temperatures of nanomechanical devices covered with aluminum. A clear excess damping is observed after switching the metallic layer from superconducting to the normal state with a magnetic field. Beyond the standard model…

High Throughput Characterization Methods at the Wafer Scale for Sputtered Films Used in Micro-Supercapacitors and Li-Ion Micro-Batteries

Pascal Roussel, Aiman Jrondi, Khac Huy Dinh, Bukola Jolayemi, Clément Leviel, Maxime Hallot, Christophe Lethien

The emergence of new miniaturized and autonomous electronic technologies leads to a request of efficient microdevices for energy storage. The development of thin film Li-ion micro-batteries or micro-supercapacitors is an interesting way to power connected sensors, as their manufacturing method is…

Effects of Reaction Parameters on the Geometry and Crystallinity of Hydrothermally Synthesized ZnO Nanorods for Bio-Fouling Applications

Abderrahmane Hamdi, Chin Sing Lim, Mohamed Aymen Ben Achour, Ali Ahmed Alshehri, Mervat Alamri, D. Deresmes, Serena Lay-Ming Teo, Denis Remiens, El Hadj Dogheche

In this present work, we have successfully synthesized vertical aligned ZnO nanorod arrays (ZnO NRs) on conductive stainless-steel substrate. These ZnO NRs were obtained by using a low temperature, low cost, and eco-friendly hydrothermal approach. The effect of the sol-gel deposited ZnO seed layer…
