Low-Temperature-grown GaAs photoconductors suitable for 1550nm-wavelength illumination

Charbel Tannoury, Maximilien Billet, Christophe Coinon, Jean-Francois Lampin, Emilien Peytavit

In this communication, we show that ultrafast photoconductors based on low-temperature-grown Gallium Arsenide material exhibit photoresponse values reaching 11 mA/W under 1550 nm CW excitation. This is obtained by using an optical microcavity based on a buried metal layer acting as back reflecting…

Antennas for a point to multi-point communication system operating in D-band

Giacomo Ulisse, Guillaume Ducournau, Viktor Krozer

Two different antennas were developed for a point to multi-point communication system operating in D-band (110- 170 GHz). The first is a horn antenna with a 20 dB gain and 30° horizontal radiation pattern. The second one is a horn antenna with a focusing dielectric lens that allows to reach a gain…

A Methodology to Estimate the Signal-to-Interference Power Ratio for Intermittent Disturbances

Artur Nogueira de São José, Eric Pierre Simon, Alexandre Boé, Thomas Vantroys, Christophe Gransart, Virginie Deniau

Estimating the signal-to-interference power ratio with traditional measuring equipment such as spectrum analyzers is not an easy task when the disturbance is intermittent. In these situations, the power may rapidly switch between its peak value and the equipment noise floor. As a consequence,…

Mitigation of substrate coupling effects in RF switch by localized substrate removal using laser processing

Arun Bhaskar, Justine Philippe, Etienne Okada, Flavie Braud, J.F. Robillard, Cédric Durand, Frédéric Gianesello, Daniel Gloria, Christophe Gaquière, Emmanuel Dubois

With the evolution of radio frequency (RF)/microwave technology, there is a demand for circuits which are able to meet highly challenging RF frontend specifications. Silicon-on-insulator (SOI) technology is one of the leading platforms for upcoming wireless generation. The degradation of…

Enhanced antibacterial activity of CuS-BSA/lysozyme under near infrared light irradiation

Abir Swaidan, Sena Ghayyem, Alexandre Barras, Ahmed Addad, Sabine Szunerits, Rabah Boukherroub

The synthesis of multifunctional photothermal nanoagents for antibiotic loading and release remains a challenging task in nanomedicine. Herein, we investigated a simple, low-cost strategy for the preparation of CuS-BSA nanoparticles (NPs) loaded with a natural enzyme, lysozyme, as an antibacterial…

Impact of GSG probe to pads contact repeatability for on-wafer RF measurements

Cerine Mokhtari, Mohamed Sebbache, Vanessa Avramovic, Christophe Boyaval, Gilles Dambrine, Kamel Haddadi

Improving the contact repeatability for on-wafer measurements is required to address accurate characterization of microwave and millimeter-wave extreme impedance devices foreseen in future RF semi-conductor industry. In this effort, residual error terms introduced by conventional on-wafer probe…

NON LOCAL AND THERMAL EFFECTS IN A BI-STABLE LATTICE

Luca Bellino, Giuseppe Florio, Stefano Giordano, Giuseppe Puglisi

We extend a previous model in order to consider interface energy terms on a bistable chain undergoing phase transition.Specifically, by including the effects of non local, next to nearest neighbor (NNN), interactions we are able to describe both thepresence of stress peak and the phase evolution…
