Available in PDF, EPUB and Kindle. Book excerpt: La photonique sur silicium est envisagée comme une solution technologique très prometteuse pour le remplacement des interconnexions électriques par des interconnexions optiques devant se produire dans les prochaines années. Des dispositifs optoélectroniques comme des sources lasers, des modulateurs et des détecteurs, ont été développés pour la réalisation de circuits intégrant des émetteurs/récepteurs. Parmi les défis devant être relevés pour faire avancé la photonique sur silicium, la réduction de la consommation électrique du modulateur est un point crucial. L'intégration des composants passifs et actifs en utilisant une seule et même technologie est également un enjeu majeur pour les futurs systèmes de communication optique. Grâce au développement de l'intégration hybride de semi-conducteurs III-V sur silicium pour la réalisation de sources laser sur silicium, de nouvelles voies peuvent être envisagée pour réaliser des modulateurs optiques et des photodétecteurs efficaces et compacts. De plus, les cristaux photoniques 2D (PhC) et spécifiquement les structures à ondes lentes, qui sont connues pour renforcer les interactions entre la lumière et la matière peuvent apporter des solutions intéressantes pour diminuer de manière ultime la puissance consommée.Dans ce contexte, les travaux menés durant ma thèse ont porté plus spécifiquement sur la conception, la fabrication et la caractérisation de modulateurs à électro-absorption à onde lente en semiconducteur III-V sur silicium. Dans une première partie consacrée à la modélisation, une attention particulière est portée à la conception du cristal photonique et au couplage de la lumière du guide silicium vers l'onde lente. Les performances de la structure optimisée sont aussi analysées, donnant un modulateur de seulement 18.75 μm de longueur fonctionnant à 15 GHz avec un taux d'extinction supérieure à 5 dB sur une gamme spectrale supérieure à 10 nm. Par la suite, l'ensemble des procédés de nanotechnologies durant la thèse pour la fabrication des dispositifs sont présentés. Enfin, les résultats expérimentaux obtenus au cours de cette thèse démontrent l'effet Stark Confiné Quantiquement et l'effet de photodétection obtenu sur les structures intégrées.Les perspectives de ce travail de thèse concernent la réalisation de circuits intégrés photoniques complets, incluant sources lasers, modulateurs à électroabsorption et photodétecteurs en utilisant une seule et même technologie.

This book was released on 2004-02-29 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon-on-Insulator Technology: Materials to VLSI, Third Edition, retraces the evolution of SOI materials, devices and circuits over a period of roughly twenty years. Twenty years of progress, research and development during which SOI material fabrication techniques have been born and abandoned, devices have been invented and forgotten, but, most importantly, twenty years during which SOI Technology has little by little proven it could outperform bulk silicon in every possible way. The turn of the century turned out to be a milestone for the semiconductor industry, as high-quality SOI wafers suddenly became available in large quantities. From then on, it took only a few years to witness the use of SOI technology in a wealth of applications ranging from audio amplifiers and wristwatches to 64-bit microprocessors. This book presents a complete and state-of-the-art review of SOI materials, devices and circuits. SOI fabrication and characterization techniques, SOI CMOS processing, and the physics of the SOI MOSFET receive an in-depth analysis. Silicon-on-Insulator Technology: Materials to VLSI, Third Edition, also describes the properties of other SOI devices, such as multiple gate MOSFETs, dynamic threshold devices and power MOSFETs. The advantages and performance of SOI circuits used in both niche and mainstream applications are discussed in detail. The SOI specialist will find this book invaluable as a source of compiled references covering the different aspects of SOI technology. For the non-specialist, the book serves an excellent introduction to the topic with detailed, yet simple and clear explanations. Silicon-on-Insulator Technology: Materials to VLSI, Third Edition is recommended for use as a textbook for classes on semiconductor device processing and physics at the graduate level.

Download or read book Molecular Beam Epitaxy written by John Wilfred Orton and published by . This book was released on 2015 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a history of Molecular Beam Epitaxy (MBE) as applied to the growth of semiconductor thin films (note that it does not cover the subject of metal thin films). It begins by examining the origins of MBE, first of all looking at the nature of molecular beams and considering their application to fundamental physics, to the development of nuclear magnetic resonance and to the invention of the microwave MASER. It shows how molecular beams of silane (SiH4) were used to study the nucleation of silicon films on a silicon substrate and how such studies were extended to compound semiconductors such as GaAs. From such surface studies in ultra-high vacuum the technique developed into a method of growing high quality single crystal films of a wide range of semiconductors. Comparing this with earlier evaporation methods of deposition and with other epitaxial deposition methods such as liquid phase and vapour phase epitaxy (LPE and VPE). The text describes the development of MBE machines from the early 'home-made' variety to that of commercial equipment and show how MBE was gradually refined to produce high quality films with atomic dimensions. This was much aided by the use of various in-situ surface analysis techniques, such as reflection high energy electron diffraction (RHEED) and mass spectrometry, a feature unique to MBE. It looks at various modified versions of the basic MBE process, then proceed to describe their application to the growth of so-called 'low-dimensional structures' (LDS) based on ultra-thin heterostructure films with thickness of order a few molecular monolayers. Further chapters cover the growth of a wide range of different compounds and describe their application to fundamental physics and to the fabrication of electronic and opto-electronic devices. The authors study the historical development of all these aspects and emphasise both the (often unexpected) manner of their discovery and development and the unique features which MBE brings to the growth of extremely complex structures with monolayer accuracy.
Download or read book TOF Range Imaging Cameras written by Fabio Remondino and published by Springer Science & Business Media. This book was released on 2013-04-09 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today the cost of solid-state two-dimensional imagers has dramatically dropped, introducing low cost systems on the market suitable for a variety of applications, including both industrial and consumer products. However, these systems can capture only a two-dimensional projection (2D), or intensity map, of the scene under observation, losing a variable of paramount importance, i.e., the arrival time of the impinging photons. Time-Of-Flight (TOF) Range-Imaging (TOF) is an emerging sensor technology able to deliver, at the same time, depth and intensity maps of the scene under observation. Featuring different sensor resolutions, RIM cameras serve a wide community with a lot of applications like monitoring, architecture, life sciences, robotics, etc. This book will bring together experts from the sensor and metrology side in order to collect the state-of-art researchers in these fields working with RIM cameras. All the aspects in the acquisition and processing chain will be addressed, from recent updates concerning the photo-detectors, to the analysis of the calibration techniques, giving also a perspective onto new applications domains.

Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.
