Modeling of a Circular Ring MEMS Resonator with Voltage Excitation by Means of an Orthogonal Polynomial Method

Ismail Naciri, Abdessamad Rguiti, Lahoucine Elmaimouni, Jean-Etienne Lefebvre, Faniry Emilson Ratolojanahary, Tadeusz Gryba

The three-dimensional vibrational behavior of a piezoelectric circular ring made of a 6 mm hexagonal material is studied using Legendre polynomial method. The method is simple to implement and based on expanding the electrical potential and the mechanical displacement components in a double series…

GaN-on-silicon high-electron-mobility transistor technology with ultra-low leakage up to 3000 V using local substrate removal and AlN ultra-wide bandgap

Ezgi Dogmus, Malek Zegaoui, F Medjdoub

We report on extremely low off-state leakage current in AlGaN/GaN-on-silicon metal–insulator–semiconductor high-electron-mobility transistors (MISHEMTs) up to a high blocking voltage. Remarkably low off-state gate and drain leakage currents below 1 µA/mm up to 3 kV have been achieved owing to the…

A simplified modal expansion formalism adapted to the optical design of resonant cavity enhanced photodetectors using metallic gratings

Maximilien Billet, Emilien Peytavit

In this communication, we present a method to model the light absorption in a resonant photoconductor based on a photoconductive layer sandwiched between a metallic grating in front side and a metallic backside mirror. We started from a modal expansion formalism previously developed in order to…

Conception and realization of highly selective band-pass filters in Ka-band built on thin polymer films

Mohammed El Gibari, Sara Bretin, Patrick Derval, S. Ginestar, Guillaume Lirzin, Hong Wu Li

A novel structure of high performance narrow band-pass filters on thin polymer film is reported in this paper. It's composed of two microstrip resonators placed between two via-free microstrip-grounded coplanar waveguide transitions. It combines therefore compactness, low-cost, fabrication…

On wafer millimetre wave power detection using a PN junction diode in BiCMOS 55 nm for in-situ large signal characterization

Joao Carlos Azevedo Goncalves, Issa Alaji, Daniel Gloria, Vincent Gidel, Frederic Gianesello, Sylvie Lepilliet, Guillaume Ducournau, Francois Danneville, Christophe Gaquière

This paper describes millimetre wave (mmW) on-wafer power detection using dedicated high frequency diode junction with a cut-off frequency (fc) of 400 GHz, integrated in SiGe BiCMOS 55 nm technology from STMicroelectronics. This extraction was performed in order to develop fully integrated power…

Dynamics of a broad-band quantum cascade laser: from chaos to coherent dynamics and mode-locking

L. Columbo, S Barbieri, C. Sirtori, M. Brambilla

The dynamics of a multimode quantum cascade laser, are studied in a model based on effective semiconductor Maxwell-Bloch equations, encompassing key features for the radiation-medium interaction such as an asymmetric frequency dependent gain and refractive index as well as the phase-amplitude…

Two dimensional modeling of elastic wave propagation in solids containing cracks with rough surfaces and friction – Part I: Theoretical background

Vladislav Aleshin, Steven Delrue, Andrey Trifonov, Olivier Bou Matar, Koen van den Abeele

Abstract Our study aims at the creation of a numerical toolbox that describes wave propagation in samples containing internal contacts (e.g. cracks, delaminations, debondings, imperfect intergranular joints) of known geometry with postulated contact interaction laws including friction. The code…

Optical and Thermal Performances of (Ga,In)N/GaN Light Emitting Diodes Transferred on a Flexible Tape

B. Damilano, Marie Lesecq, Di Zhou, Éric Frayssinet, Sebastien Chenot, Julien Brault, N. Defrance, Abel Ebongue, Y. Cordier, Virginie Hoel

Blue (Ga,In)N-based light-emitting diodes (LEDs) grown on a Si(111) substrate by metal-organic vapor phase epitaxy are transferred on a flexible tape after the Si substrate removal. Their optical and thermal behaviors are measured and compared to those of regular LEDs on Si. The light output power…

Optical transmission properties of an anisotropic defect cavity in one-dimensional photonic crystal

Noama Ouchani, Abdelaziz El Moussaouy, Hassan Aynaou, Youssef El Hassouani, El Houssaine El Boudouti, Bahram Djafari-Rouhani

We investigate theoretically the possibility to control the optical transmission in the visible and infrared regions by a defective one dimensional photonic crystal formed by a combination of a finite isotropic superlattice and an anisotropic defect layer. The Green's function approach has…
