Book Description
En este libro se presentan los fundamentos físicos y tecnológicos de los dispositivos electrónicos actuales (propiedades eléctricas y ópticas de los semiconductores, unión PN, contactos metal-semiconductor y tecnología de fabricación de dispositivos y circuitos integrados), así como la teoría y la tecnología de diversos dispositivos prácticos como diodos, transistores bipolares, transistores de efecto de campo (MOS, JFET, MESFET) y dispositivos optoelectrónicos (fotoconductores, células solares, fotodiodos, fototransistores, diodos emisores de luz y diodos láser). Este contenido se corresponde básicamente con el temario de la asignatura Dispositivos Electrónicos y Fotónicos que cursan los estudiantes de Ingeniería Electrónica que se imparte en la ETSETB de la UPC. Este texto se ha desarrollado en el marco de una experiencia de enseñanza no presencial que se ha llevado a cabo en los referidos estudios. Por este motivo, contiene gran cantidad de ejercicios resueltos (136), de ejemplos de casos prácticos (58), de cuestiones cualitativas y cuantitativas (310) y de problemas guiados (21), que se proponen al lector con el objetivo de provocar una reflexión y una profundización de los conceptos presentados. Las soluciones de las cuestiones y de los problemas guiados están disponibles a través del programa interactivo DELFOS (véase el anexo C de este libro), que puede obtenerse por Internet siguiendo las instrucciones de la página web: http://www.edicionsupc.es/poli131.

Book Description
El Año Internacional de la Luz y las Tecnologías Basadas en Luz 2015 fue una iniciativa global adoptada por las Naciones Unidas. Numerosas organizaciones culturales, académicas, industriales y gubernamentales alrededor del mundo unieron fuerzas para celebrar la luz y crear conciencia sobre las muchas maneras en que la fotónica impacta nuestras vidas en áreas como la energía, educación, cambio climático, salud y bienestar social. De la iniciativa resultaron miles de actividades que involucraron a millones de personas en más de 100 países del mundo. Los temas de este volumen surgieron a lo largo de 2015 como los más relevantes y con mayor interés. Se espera que este libro se convierta en un documento de consulta básica y un legado imborrable.

Book Description
Optical communication using optical fibres as the transmission medium is essential to handling the massive growth of both telecom and datacom traffic. To fully realize the potential bandwidth available on these optical fibres, other components of the optical network system have to be developed, ranging from detectors and multiplexers to buffers and switches. This book addresses the different technologies which can be applied to switching optical signals.An optical switch functions by selectively switching an optical signal delivered through an optical fibre or in an integrated optical circuit to another. Several methods are available and each relies on a different physical mechanism for its operation. The various physical mechanisms used are discussed in the main chapters in the book which cover electro-optical, thermo-optical, micro-electro-mechanical (MEMS)-based and semiconductor optical amplifier (SOA)-based optical switches. The book also covers switching based on optical nonlinear effects, liquid and photonic crystal optical switches as well as fibre, holographic, quantum optical and other types of optical switches. Each chapter discusses the choice of materials, fabrication techniques and key issues in switch design.With its distinguished editors and international team of contributors, Optical switches: materials and design is a standard reference for the telecommunications industry and those researching this important topic. - Reviews this commercially significant area of research and addresses the different technologies which can be applied to switching optical signals - Provides a balanced look at the developments which can be defined as key trends in optical switches - Major optical switches including electro-optical, thermo optical and magneto-optical switches are discussed and the respective theory and principles of each explored

Book Description
Optical Transmission represents a wide set of visions of researchers who are active in the actual research scene in Europe. An aggregate of highlights of research in transmission with a state of the art presented by the researchers who are driving it are presented. The trends on research are in this book presented by one of the widest networks of excellence put together in Europe in the field of optical networking (more than 40 Research institutions were involved). The readers will find a specialized readout of the current trends and status of transmission ranging from simulation to ultimate experimental results, from modulations to devices. A highlight of Optical Transmission is the introduction in a technical book a chapter on techno-economics, which drives the vision and field a little further. General reading could be made however is more suited for graduated users. The most important features of Optical Transmission are: wide vision on transmission related issues, state of the art and related trends and techniques; techno-economics of the field.

Book Description
This Special Publication contains 43 scientific studies presented at the 5th conference on ‘Clays in natural and engineered barriers for radioactive waste confinement’ held in Montpellier, France in 2012. The conference and this resulting volume cover all the aspects of clay characterization and behaviour considered at various temporal and spatial scales relevant to the confinement of radionuclides in clay, from basic phenomenological process descriptions to the global understanding of performance and safety at repository and geological scales. Special emphasis has been given to the modelling of processes occurring at the mineralogical level within the clay barriers. The papers in this Special Publication consider research into argillaceous media under the following topic areas: large-scale geological characterization; clay-based concept/large-scale experiments; hydrodynamical modelling; geochemistry; geomechanics; mass transfer/gas transfer; mass transfer mechanisms. The collection of different topics presented in this Special Publication demonstrates the diversity of geological repository research.
