500 GHz operational bandwidth MUTC-photodiodes with milliwatt terahertz output power levels

Ezgi Abacıoğlu, Marcel Grzeslo, Tom Neerfeld, Abdu Subahan Mohammed, J L F Estévez, Guillaume Ducournau, Andreas Stöhr

We present waveguide-integrated 1.55 μm InP-based modified uni-travelling-carrier photodiodes (MUTC-PDs) featuring coplanar waveguide outputs. The fabricated photodiodes yield an operational bandwidth of 500 GHz and milliwatt output power levels in the lower THz domain.

Autonomous radar interference detection and mitigation using neural network and signal decomposition

Dayat Kurniawan, Budiman Putra Asmaur Rohman, Ratna Indrawijaya, Chaeriah Bin Ali Wael, Suyoto Suyoto, Purwoko Adhi, Iman Firmansyah

Autonomous radar interference is a challenging problem in autonomous vehicle systems. Interference signals can decrease the signal-to-interference-noise ratio (SINR), and this condition decreases the performance detection of autonomous radar. This paper exploits a neural network and signal…

Time-encoded electrical detection of trace RNA biomarker by integrating programmable molecular amplifier on chip

Gurpreet Kaur, Marcel Tintelott, Mohit Suranglikar, Antoine Masurier, Xuan-Thang Vu, Guillaume Gines, Yannick Rondelez, Sven Ingebrandt, Yannick Coffinier, Vivek Pachauri, Alexis Vlandas

One of the serious challenges facing modern point-of-care (PoC) molecular diagnostic platforms relate to reliable detection of low concentration biomarkers such as nucleic acids or proteins in biological samples. Non-specific analyte-receptor interactions due to competitive binding in the presence…

Fault detection and localization in unshielded twisted pair cable based on observability analysis and reflectometry experimental measurements.

Hermine Judith Idellette Som, Vincent Cocquempot, Virginie Degardin

In this paper, an efficient method is proposed for detecting and locating a soft fault, i.e. a physical degradation, in a Y -shaped network of unshielded twisted pair cables. The method uses jointly the observability analysis and time-frequency domain reflectometry experimental measurements. The…

Retention or repulsion forces induced by bubbles trapped at the base of an immersed microparticle on a substrate

Anna Ipatova, Alexis Duchesne, H N Yoshikawa, Pascal Mariot, Corenthin Leroy, Christine Faille, Ichiro Ueno, Georg F Dietze, Farzam Zoueshtiagh

We explore the potential for air bubble entrapment beneath micrometer-sized particles following immersion. This investigation employs theoretical, numerical, and experimental methodologies, with a focus on the wetting characteristics of both the particle and its substrate. These properties are…

Thermoelectric Properties of Benzothieno-Benzothiophene Self-Assembled Monolayers in Molecular Junctions

Sergio Gonzalez-Casal, Rémy Jouclas, Imane Arbouch, Yves Geerts, Colin van Dyck, Jérôme Cornil, Dominique Vuillaume

We report a combined experimental (C-AFM and SThM) and theoretical (DFT) study of the thermoelectric properties of molecular junctions made of self-assembled monolayers on Au of thiolated benzothieno-benzothiophene (BTBT) and alkylated BTBT derivatives (C8-BTBT-C8). We measure the thermal…

Continuously Beam-Steered Phased Array Antenna Using GaN Varactors for Millimeter-Wave Applications

Abdelaziz Hamdoun, F Medjdoub, Mohamed Himdi, Malek Zegaoui, Olivier Lafond

A continuously steerable beam patch antenna array employing a classical phase shifter based on GaN HEMTs is presented. Here, the GaN HEMTs are used as varactor diodes to achieve the tunability purpose. By controlling the DC bias of these varactors from −2 V to 2 V, the proposed array antenna can…

Fabry-Pérot and Friedrich-Wintgen bound states in the continuum in a photonic triple-stub cavity

Yamina Rezzouk, Soufyane Khattou, Mohamed El Ghafiani, Madiha Amrani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

Bound states in the continuum (BICs) are zero-width (infinite lifetime) trapped eigenmodes that remain conf ined in the system even though they coexist with a continuum of extended states. The resulting high-frequency resonances may have significant applications in photonic integrated circuits,…
