Near-infrared wafer-fused vertical-cavity surface-emitting lasers for HF detection

Elyahou Kapon, Grigore Suruceanu, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman

1310 nm Wavelength VCSELs produce single mode emission in excess of 1 mW in the temperature range of 20-70 degrees C with a very low relative intensity noise of -148 dB/Hz. These devices have a broad tuning range of similar to 50 cm(-1) with variable tempe ...

Dielectric properties of silver nanoparticles coated with silica shells of different thicknesses

Heinrich Hofmann, Jose Enrico Quijano Quinsaat

Core/shell nanoparticles having metallic silver nanoparticle cores of similar to 38 nm in diameter and silica shells of different thicknesses ranging from similar to 3.6-20 nm were prepared. For the silica coating, a slightly modified Stober method was use ...

About tuning capacitors in inductive coupled power transfer systems

Yves Perriard, Paolo Germano, Christophe Bruno Auvigne

Inductive Coupled Power Transfer (ICPT) is a widely used technique to transfer electrical power from a power supply to one or more load(s) without any physical link. Even with large airgaps between primary and secondary coils, a very high power transfer ef ...

Integrated active tracking detector for MRI-guided interventions

Giovanni Boero, Jens Anders, Paul Sangiorgio

We present a fully integrated detector suitable for active tracking of interventional devices in MR-guided interventions. The single-chip microsystem consists of a detection coil, a tuning capacitor, an intermediate frequency downconversion receiver, and a ...

A 2.4-GHz MEMS-based PLL-free multi-channel receiver with channel filtering at RF

Christian Enz, Aravind Prasad Heragu Singaiyengar

A low power 2.4-GHz receiver exploiting the intrinsic high quality factor (Q) of Bulk Acoustic Wave (BAW) resonators is presented. A novel way of performing simple integer division of the BAW digitally controlled oscillator (DCO) signal to address multi-ch ...

Système de conversion d'énergie

Yves Perriard, Paolo Germano, Christophe Bruno Auvigne

The system (20) has a switching unit (T1) adapted for switching reversibly between two configurations. A capacitor is connected in series between a secondary winding (9) and a connection terminal (A) in one of the configurations. Another capacitor is conne ...

Proof of concept of a dual-band circularly-polarized RF MEMS beam-switching reflectarray

Julien Perruisseau-Carrier, Caner Güçlü

In this communication we propose the concept of a circularly polarized reflectarray (RA) antenna capable of independent beam-switching in both K and Ka bands. The RA unit cell comprises one microstrip ring per each operation frequency. Each ring is integra ...
