Analysis and Design of an Integrated Compact RF Driving System for PIC-Based Hybrid AOM Phase Shifters for Free Space Optical Communication

Jurgen Vanhamel, Samuel Dupont, Rudolf Saathof

When using Radio Frequency aboard small satellites, for high data rates, this would need large antennas, violating constraints related to size, weight, and power. As an alternative, Free Space Optical Communication (FSOC) uses laser beams, operating in the optical and infrared frequency domain, in…

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…

Atomic Clocks Based on Hot Alkali Vapor Microfabricated Cells

Rodolphe Boudot, Nicolas Passilly, Vincent Maurice, Emmanuel Klinger, Quentin Tanguy, Carlos-Manuel Rivera-Aguilar, Clément Carlé, Moustafa Abdel Hafiz, Andrei Mursa

We summarize recent activities performed at FEMTO-ST on the development of high-stability clocks and references based on hot alkali vapor microfabricated vapor cells. By combining pulsed Ramsey-based interrogation protocols and cells built with low-permeation glass wafers, CPT-based microwave…
