REVEAL: A Retrieval-Augmented Generation Approach for Contextual Identification of Synthetic Visual Content

Mamadou Keita, Wassim Hamidouche, Hessen Eutamene, Abdelmailk Taleb-Ahmed, Abdenour Hadid

Detecting AI-generated images remains a major challenge due to the limited robustness and generalizability of existing methods, which often rely on low-level artifacts or features specific to particular generative models. These limitations reduce their effectiveness against unknown models or under...

Thermo-optic coefficient of single-crystal thin-film barium titanate on insulator

Hong-Lin Lin, Yuhui Yin, Lea Roos, El Hadj Dogheche, Aaron Danner

We report the thermo-optic coefficient (TOC) of single-crystalline barium titanate (BTO) thin film on dysprosium scandate (DSO) at 1550 nm, determined using both prism coupler measurements and an integrated thermo-optic Mach–Zehnder interferometer (TO MZI). The prism coupler, combined with...

RF Antenna Design and Integration for Neuromorphic Devices

Romain Alcesilas, Divitha Seetharamdoo, David Sodoyer, Kevin Carpentier, François Danneville, Christophe Loyez

Neuromorphic devices are systems made up of artificial neurons that replicate the function of biological neurons by generating spike trains. It offers several advantages for sensing such as the encoding of the measured signal in space and time domains with a very low power consumption. Integrating...

Dissipative layers for HSQ resist nanopatterning by E-beam lithography on insulating substrates, Couche dissipative pour nanostructuration de résine HSQ par lithographie électronique sur substrat isolant

Anne-Sophie Vaillard, Yves Deblock, Pascal Tilmant, David Guérin, Christophe Boyaval, Giuseppe Di Gioia

Dissipative layer is a key element in nanopatterning resist such as HSQ on insulating substrates. At IEMN we are currently investigating different strategies to avoid surface charging effect. Since a single top layer of Ge or Au leads to non-conform patterning, the first approach involves..., La couche dissipative est un élément clé dans les résines nanostructurées telles que le HSQ sur des substrats isolants. À l'IEMN, nous étudions actuellement différentes stratégies pour éviter l'effet de charge superficielle. Étant donné qu'une seule couche supérieure de Ge ou d'...

Ultra-Low-Power Neuromorphic Spike Detector for Large-Scale Neural Interfaces

Louis Regnacq, Hicham Lahrach, Anna Kobzar, Rédha Kassi, Pascal Mariot, A. Cappy, Christel Vanbesien, Alexis Vlandas, Christophe Loyez, Virginie Hoel

Neural interfaces are rapidly scaling, now featuring thousands of electrodes that record simultaneously. As channel counts grow, design constraints become increasingly stringent: implants must remain compact and ultra–low power while managing massive data streams. With data rates often exceeding...
