Neuromorphic Coincidence Detector for Interaural Time Difference Encoding and Sound DOA Estimation

Eugénie Dalmas, François Danneville, Michael Bocquet, Christophe Loyez

Eight decades ago, the medial superior olive (MSO) responsible for the extraction of the interaural time difference (ITD) was described as a combination of coincidence detection neurons and delay lines by Jeffress, a model largely used in spiking sound source localization systems. Coincidence...

Surface acoustic wave confinement inside uncorrelated distributions of subwavelength scatterers

Thibault Deletang, Adnane Noual, Bernard Bonello, Roman Buisine, Yan Pennec, Bahram Djafari-Rouhani

We report an experimental study of surface acoustic wave (SAW) localization and propagation in random metasurfaces composed of Al scatters using pump–probe spectroscopy. Thanks to this technique, wideband high frequency acoustic modes are generated, and their dynamical propagation directly from...

Terahertz molecular water laser using quantum cascade laser pumping

L. Juppet, Alexandra Khabbaz, J. Lampin, O. Pirali

Molecular lasers pumped by quantum cascade laser (QCL) open new possibilities for THz generation and its numerous applications, in particular, for high resolution molecular spectroscopy. In this article, a THz water laser pumped by a mid-infrared QCL was demonstrated using the broad tunability of...

Demonstration of avalanche capability in 800 V vertical GaN-on-Silicon diodes

Youssef Hamdaoui, Idriss Abid, Sondre Michler, Katir Ziouche, F Medjdoub

High-quality pseudo-vertical p-n diodes using a GaN-on-silicon heterostructure are reported. An optimized fabrication process including a beveled deep mesa as edge termination and reduced ohmic contact resistances enabled high on-state current density and low onresistance. A uniform breakdown...
