Full textThe evolution of the communication systems makes the considerable progress every year and remains a strong sector of the development of the microelectronic industry. The future developments require and imply the integration of the devices ultra high frequencies and more especially the non reciprocal passive components (insulators, circulators, ferrite modulators). The planar structures are those wich are used thanks to their simple configuration and they permit the connection in surface without "via". Obtaining of the non reciprocal effects on a ferrite coplanar line is the subject of our work. We develop in this thesis the computer codes using the TLM method (Transmission Line matrix), wich is well adapted to this kind of problem, to treat the anisotropic and the dispersive mediums to arrive to modeling of the insulator coplanar guide using the gyromagnetic resonance

Full textThe thesis subject dealt in this report lies in the LE²P framework on the energy sustainability of wireless sensor network. This work is dedicated to the reception and rectifying part of wireless power transfer to give energy sustainability to nodes in a sensor network. This process is not new and originate from the years 1950. The behavior of this process is since well-known in several waveguide such technology as microstrip. But the need of drill in those waveguide circuit may be inconvenient and lead to discrepancy from one circuit to another. This was the motivational keystone to the work address in this report which uses coplanar waveguide (CPW) over microstrip. The conception of such devices goes through a good conceptual and experimental understanding of the waveguide technology. The approach in this document consists of using coplanar waveguide while minimizing its drawbacks, in order to avoid drilling in the substrate and ease the realization of the rectifying part by limiting the human interaction

Full textIn the general context of the European nanoelectronics industry, it is necessary to develop new on-wafer characterisation techniques and instruments for precise and fine validation of circuits designed for high-frequency (HF) applications. To advance the miniaturisation of HF devices, new metrological issues related to dimensional and electrical characterization must be addressed. A universal instrument for the characterization of RF devices consists of a vector network analyzer (VNA), a measurement station equipped with a pair of ground-signal-ground (GSG) microwave probes aligned manually or automatically using a microscope or a camera system on calibration substrates and devices under test (DUT). Conventional RF test structures require to adapt to the probe tip geometry. The positioning of the probe on the CPW test structure generates misalignment measurement errors that affect the reproducibility of the measurement. In addition, nanodevices have extreme impedances compared to the VNA's reference impedance of 50 Ω, resulting in poor measurement sensitivity and accuracy.To meet this challenge, a new fully automated and robotic on-wafer probing station was designed and built from scratch. The measurement probes as well as the chuck hosting the device under test are mounted on SmarAct® piezoelectric nanopositioners. The vision of the probe-to-DUT contact is provided by a high-resolution microscope camera. A Keysight® Streamline vector network analyzer was integrated into the station to obtain a compact solution close to the probes and thus reduce the non-systematic errors inherent in environmental variations. Finally, a program for driving the probes and chuck based on image recognition was developed with the LabVIEWTM software

Full textThis work focuses on high-performance S-CPW (Shielded CoPlanar Waveguide) transmissionlines in classical CMOS integrated technologies for the millimeter-wave frequency band.Thanks to an important slow-wave phenomenon, the physical length of S-CPW decreases by afactor from 1.3 to 3.2 compared with classical transmission lines. Presenting also lowattenuation loss, the developed transmission lines show very high quality factor (higher than 40at 60 GHz). The precise study of the electromagnetism field leads to an electrical model forS-CPWs. This is the first model that takes the losses in this topology into account. Then, somebasic passive circuits designed with S-CPWs and characterized up to 110 GHz are presented invarious CMOS technologies. The low insertion losses and relative low surfaces of a powerdivider and a passband filter show the great interest of S-CPW to integrate compact passivecircuits in classical CMOS technologies at millimeter-wave frequencies

Full textPour les dispositifs actifs, le composant développé est une hétérostructure à simple barrière qui présente des non-linéarités en capacité extrêmement marquées utilisables dans les multiplicateurs de fréquences. Par rapport aux dispositifs Schottky varactors conventionnels, les hétérostructures permettent de tirer parti de propriétés de symétrie et d'optimiser et d'optimiser au mieux les caractéristiques des courants de déplacement et de conduction. En pratique, les composants sont fabriqués à partir de multiples hétérostructures épitaxiées par jets moléculaires sur substrat InP mettant en jeu des techniques d'intégration monolithiques. Plusieurs séries d'échantillons ont été fabriquées avec pour les dernières structures des résultats à l'état de l'art, notamment avec la possibilité de moduler la capacité dans un rapport 5 en tenue en tension de plus de 6 Volt favorable aux applications de puissance. dans cette optique, nous démontrons par ailleurs la possibilité d'intégrer verticalement plusieurs composants sur une même épitaxie.
Pour les structures passives, elles sont constituées de lignes coplanaires déposées sur membrane de polyimide ou de nitrure de silicium. Dans ces conditions le milieu de propagation peut se comparer à l'air avec une permittivité effective très proche de celle obtenue dans l'espace libre. De telles structures ont été fabriquées en utilisant des technologies de micro-usinage de l'Arséniure de Gallium. Les résultats des caractérisations hyperfréquences sont conformes aux prédictions théoriques, avec la propagation faible perte de l'énergie électromagnétique sans dispersion dans une très large bande de fréquence. Ces études sont ensuite étendues à la conception de structures de filtrage aux fréquences millimétriques, notamment à 250 GHz.

Full textSpin-waves have been proposed as a possible technological path to overcome the hurdles encountered by the miniaturization of complementary metal-oxide-semiconductor (CMOS) into the nanometer range, demonstrated by recent developments in spin-wave-based logic devices. However the industrial appeal of these proofs-of-concept is conditional upon their scalable integration with CMOS technology. Here, we report on ultrathin Ta/CoFeB/MgO wires used as spin-wave waveguides. This system is chosen for its compability with CMOS processes, its perpendicular magnetic anisotropy and strong spin-orbit interactions. The latter are of interest for manipulating spin waves and are characterized via spin-torque ferromagnetic resonance where it is shown that the inverse spin Hall effect is responsible for the detection of magnetization dynamics. Following this, we use integrated nanometric coplanar waveguides to locally excite spin-waves in a broad range of wavevectors. Comparison of the measured spin-wave spectrum with analytical calculations show that the inverse spin Hall effect allows the wavevector-independent detection of spin-waves with wavelengths down to 150 nm. Complementary Brillouin light scattering experiments reveal that spin-waves in the ultrathin spin-wave waveguide with perpendicular magnetic anisotropy have unexpectedly high propagation lengths considering the relatively high damping in Ta/CoFeB/MgO systems. These findings pave the way for ultrathin CMOS-compatible spin-wave devices with excitation and detection techniques that are scalable into the nanometer range, with the prospect of controlling spin-waves via spin-orbit torques

Full textLn recent years, extensive research and development efforts have been put into exploiting planar filters for their potential qualities of low cost, tiny weight and high degree of integration. The aim of the research work presented in this manuscript is the design and the realization of selective and miniaturized planar filters. A new topology of compact low-pass filter with periodic structures, constituted by a transmission line loaded by SMT capacitors, is proposed. A rigorous design method for the low-pass filter is also implemented. The measurements of the low-pass filters, realized ne al' to 1 GHz in a CPW technology, in good agreement with simulations demonstrated interesting electrical proprieties of rejection, matching and spurious suppression. The validity of this topology is also investigated for higher frequencies with the realization of a low-pass filter in the K-band. Several capacitor's characterization approaches were also investigated. The implementation of capacitors in a low pass filter with periodic structure carried out constitutes the most precise way to characterize capacitors. A new topology of Ultra Wide Band band-pass filters, based on the combination of a high pass filter with short circuited stubs and a low pass filter with capacitively loaded lines, is proposed, The measurements of the prototype filters realized in a microstrip teclmology, in good agreement with simulations, show interesting proprieties of selectivity, miniaturization and spurious suppression

Full textThis thesis presents a nanophotoswitch with integrated optics for the optical sampling of radar signals. The photoswitch is a microwave coplanar waveguide fabricated on a semi-insulating GaAs substrate or a low temperature GaAs substrate, which has a gap that can be either top illuminated by an optical fiber or illuminated by an integrated optical waveguide. We started with semi-insulating GaAs devices.The center conductor of the first components has two triangular microwave tapers with a submicronic gap located at the center. We measured an ON/OFF ratio greater than 13 dB up to 20 GHz, by top illumination.We worked on the geometry of the coplanar waveguide. We particularly studied exponential and sinusoidal tapers and the effect of a decrease of the conductor spacing. We have measured a 32 dB ON/OFF ratio up to 20 GHz, and 6.5 dB of insertion losses.We studied by beam propagation method different types of dielectric guides. For the integrated device, we chose nanowaveguides with a Si3N4 core buried in a SiO2 matrix, which can be fabricated on a gold deposit. We measured an ON/OFF ratio greater than 25 dB up to 20 GHz.Nanophotoswitches built on a low temperature GaAs substrate have been put into a sampling system comprising a femtosecond pulsed laser, and we have subsampled a 20 GHz signal with a 3.15 effective number of bits

This research involves the design and evaluation of an optical interconnect module with non-coplanar dual waveguide paths. The primary feature of this module is a split optical path that can be used for transmission of optical signals within a chip or between chips, and can also be used to check the integrity of the optical signal. The module can serve as an optical interconnect framework between active electronic components and passive photon components are opposite side. The non-coplanar optical coupling is accomplished in the following manner. A 1550 nm infrared source first passes through a SOI substrate and is reflected from a 45-degree optical quality surface. It is then split into dual optical paths. Then it’s by using the 45-degree reflect surface to reflect the dual optical paths through the SOI substrate to active electronic component receiver to integrate the optical- electrical signal. The proportion of optical intensity is able to be adjusted by changing the width of waveguide that pass through the 45-degree reflect surface. Even further to get different proportion of optical intensity. This non-coplanar dual waveguide of optical paths includes 45-degree reflection groove, trapezoidal ridge waveguide and optical splitter waveguide. A laboratory model of the module was designed, fabricated, and key optical performance characteristics were evaluated. The insertion loss of upper-base-width 40~75μm non-coplanar bending waveguide is -3.04 to -3.22 dB. The total insertion loss of upper-base-width 40~75 μm non-coplanar dual waveguide is between -3.46 to -3.9 dB. Compared with non-coplanar bending waveguide, the total insertion loss averagely increases 0.51 dB. The measurements of insertion loss of upper-base-width 40 ~ 75 μm non-coplanar waveguide are -4.72 ~ -6.13 dB on optical path 1, and -11.48 ~ -6.86 dB on optical path 2. The proportion of optical intensity of dual optical path can be adjusted from 8.3 : 1.7 to 5.4 : 4.6, with the increase of upper-base- width, optical path 1 decrease and optical path 2 increase. Optical single mode fiber misalignment tolerance was also measured. For the 45 μm width module, 50 μm in path 1 and 50 μm in path 2 resulted in a horizontal (x-axis) loss of 1 dB, while for a 1 dB vertical (z-axis) loss, the corresponding tolerances were 26 μm for path 1 and 24 μm for path 2, respectively. For the 55 μm width module, the corresponding tolerances were 52 μm and 37 μm (horizontal 1 dB) and 25 μm and 20 μm (vertical 1dB), respectively.
