Observation of two-dimensional acoustic bound states in the continuum

Marc Martí-Sabaté, Junfei Li, Bahram Djafari-Rouhani, Steven Cummer, Dani Torrent

Abstract The design of devices based on acoustic or optical fields requires the fabrication of cavities and structures capable of efficiently trapping these waves. A special type of cavity can be designed to support resonances with a theoretically infinite quality factor, named bound states in the…

High conversion efficiency photonic THz mixers based on iron-doped InGaAs embedded in a plasmonic microcavity

Victor Merupo, Charbel Tannoury, Giuseppe Di Gioia, David Troadec, Yves Deblock, Steffen Breuer, Robert Kohlhaas, Emilien Peytavit

We present an optoelectronic mixer for the terahertz (THz) frequency-domain based on an iron-doped InGaAs layer integrated in a plasmonic microcavity. We show that this structure, under 1550-nm-wavelength illumination, allows for more than 70% absorption efficiency in a 220 nm-thin InGaAs absorber…

THz coherent source based on light structuration using III-V semiconductor laser technology

Adrian Bartolo, Mohamed Nadrani, Baptiste Chomet, Alaeddine Abbes, Nathan Vigne, Grégoire Beaudoin, Mathias Marconi, Luc Le Gratiet, Konstantinos Pantzas, Annick Pénarier, Philippe Nouvel, Guillaume Ducournau, Ping-Keng Liu, Mona Jarrahi, Massimo Giudici, Isabelle Sagnes, Arnaud Garnache, Stéphane Blin

THz photonics-based sources are attractive as they offer room-temperature solutions that rely on mature photonics technology and provide broadband tunability and large modulation bandwidth to address specific THz applications such as high-data-rate communications or spectroscopy. We will present an…

Challenges in developing bidirectionnal neurobiohybride interfaces

Anna Kobzar, Nathan Schoonjans, Dimitri Henniquau, Vanessa Avramovic, Pascal Mariot, Valerio Farfariello, David Delcroix, Rédha Kassi, A. Cappy, Alexis Vlandas, Virginie Hoel, Christel Vanbesien

Neurobiohybrid (NBH) interfaces are defined as a tripartite system composed of living neurons, an interface and an artifact able to stimulate and/or record electric activity from living cells (Vassanelli & Mahmud, 2016). Such systems are used not only as in vitro research platforms but also as…

High-speed and acceleration micrometric jets induced by GHz streaming: A numerical study with direct numerical simulations

Virginie Daru, Bjarne Vincent, Michael Baudoin

Gigahertz acoustic streaming enables the synthesis of localized microjets reaching speeds of up to meters per second, offering tremendous potential for precision micromanipulation. However, theoretical and numerical investigations of acoustic streaming at these frequencies remain so far relatively…

[Review] State of the art and future research directions of materials science applied to electrochemical biosensor developments

Erich Kny, Roger Hasler, Wiktor Luczak, Wolfgang Knoll, Sabine Szunerits, Christoph Kleber

Centralized laboratories in which analytical processes are automated to enable the analysis of large numbers of samples at relatively low cost are used for analytical testing throughout the world. However, healthcare is changing, partly due to the general recognition that care needs to be more…
