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…

Molecular Detection of SARS-CoV-2 Viral Particles in Exhaled Breath Condensate via Engineered Face Masks

Hannes Dörfler, John Daniels, Shekhar Wadekar, Quentin Pagneux, Dennis Ladage, Georg Greiner, Ojan Assadian, Rabah Boukherroub, Sabine Szunerits

Background: Exhaled breath condensate (EBC), defined as the condensed water vapor fraction from exhaled breath, rep- resents a largely untapped diagnostic medium for lung-related diseases. This study features a novel non-invasive approach for the collection of EBC using engineered face masks. We…
