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.

Imaging nanomechanical vibrations and manipulating parametric mode coupling via scanning microwave microscopy

Hao Xu, Srisaran Venkatachalam, Toky Harrison Rabenimanana, Christophe Boyaval, Sophie Eliet, Flavie Braud, Eddy Collin, Didier Theron, Xin Zhou

In this study, we present a novel platform based on scanning microwave microscopy for manipulating and detecting tiny vibrations of nanoelectromechanical resonators using a single metallic tip. The tip is placed on the top of a grounded silicon nitride membrane, acting as a movable top gate of the…

2D Rhenium- and Niobium-Doped WSe₂ Photoactive Cathodes in Photo-Enhanced Hybrid Zn-Ion Capacitors

Monaam Benali, Jalal Azadmanjiri, Martin Loula, Zhongquan Liao, Rui Gusmão, Amutha Subramani, Kalyan Jyoti Sarkar, Rabah Boukherroub, Zdeněk Sofer

Designing a multifunctional device that combines solar energy conversion and energy storage is an appealing and promising approach for the next generation of green power and sustainable society. In this work, we fabricated a single-piece device incorporating undoped WSe$_2$, Re- or Nb-doped WSe$_2…

Creative Mind: Hyperconnected or Disconnected ?, Créativitée: hyperconnectée ou déconnectée ?

Christophe Krzeminski

Creativity is the subject of many views. In liberal viewpoint, creativity is considered as the core of the "economical competitivity" being a key driver in terms of change rate and economical growth. The intellectual vision often seen creativity as a reflection, a mirror of our…

Improvement of linearity in trap-rich substrates for radio frequency applications: Which of donor and acceptor trap is the best?

Justine Philippe, Jean-François Robillard, Daniel Gloria, Emmanuel Dubois

This paper investigates the effect of volume traps intentionally introduced into a silicon-on-insulator (SOI) substrate by inserting a layer of polysilicon beneath buried oxide. In radio frequency applications, this type of substrate, referred to as trap-rich, is known to considerably reduce the…

D-band Modulated Signal Generation using Photonics Techniques

Yewulsew Manale Wodaje, B. Baridi, O. Occello, Francois Danneville, P. Szriftgiser, Guillaume Ducournau

D-band communications are envisioned for the next frequency step for- ward to support the future back-haul net- works. Beyond technology developments that aim to tackle circuits and systems, testing approaches also need to support the frequency upgrade of systems. This paper presents the photonics…

Robust automotive radar interference mitigation using multiplicative-adaptive filtering and Hilbert transform

Budiman Putra Asmaur Rohman, Arief Suryadi Satyawan, Dayat Kurniawan, Ratna Indrawijaya, Chaeriah Bin Ali Wael, Nasrullah Armi

Radar is one of the sensors that have significant attention to be implemented in an autonomous vehicle since its robustness under many possible environmental conditions such as fog, rain, and poor light. However, the implementation risks interference because of transmitting and/or receiving radar…

Vertical and lateral manipulation of single Cs atoms on the semiconductor InAs(111)A

Rian A. M. Ligthart, L. Desplanque, X. Wallart, Ingmar Swart, Christophe Coinon

The tip of the scanning tunneling microscope can be used to position atoms and molecules on surfaces with atomic scale precision. Here, we report the controlled vertical and lateral manipulation of single Cs atoms on the InAs(111)A surface. The Cs adatom adsorbs on the In-vacancy site of the InAs(…

Short-time expansion of one-dimensional Fokker-Planck equations with heterogeneous diffusion

Tom Dupont, Stefano Giordano, Fabrizio Cleri, Ralf Blossey

We formulate a short-time expansion for one-dimensional Fokker-Planck equations with spatially dependent diffusion coefficients, derived from stochastic processes with Gaussian white noise, for general values of the discretization parameter 0 ⩽ α ⩽ 1 of the stochastic integral. The kernel of the…
