Stability of signals generated with a dual-frequency laser and a UTC photodiode up to 700 GHz

Joachim Börner, Guillaume Pillet, Loïc Morvan, Daniel Dolfi, Alexandre Beck, Philipp Latzel, Fabio Pavanello, Guillaume Ducournau, Jean-Francois Lampin

Low phase noise and tunable THz-signals from 300 GHz to 1 THz are obtained with a combination of a unitravelling carrier photodiode and a solid-state dual-frequency laser at 1.5 μm. The spectral purity is precisely characterized. Phase noises as low as -20 dBc/Hz at 1 kHz offset from the carrier…

Dual-purpose BGaN layers on performance of nitride-based high electron mobility transistors

Vinod Ravindran, Mohamed Boucherit, Ali Soltani, Simon Gautier, Tarik Moudakir, Jeramy Dickerson, Paul L. Voss, Marie-Antoinette Di Forte-Poisson, Jean-Claude de Jaeger, Abdallah Ougazzaden

A GaN/ultrathin BGaN/GaN heterojunction is used in AlGaN/GaN high electron mobility transistors (HEMTs) to provide an electrostatic barrier to electrons and to improve the confinement of the 2-dimensional electron gas. BGaN back-barrier layers limit leakage in the GaN buffer thanks to two effects:…

Magnetostatic micro-actuator based on ultrasoft elastomeric membrane and copper-permalloy electrodeposited structures

Jérémy Streque, Abdelkrim Talbi, Clément Bonnerot, Philippe Pernod, Vladimir Preobrazhensky

This paper presents different designs of magnetostatic micro-actuators, based on both conventional and integrated micro-coils. A 3-dimensional magnetic circuit made of Permalloy is proposed in order to improve their efficiency. The mobile parts of the micro-actuators are made of ultrasoft…
