Photon Working Switches

Download or read book Photon-Working Switches written by Yasushi Yokoyama and published by Springer. This book was released on 2017-05-29 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on photoswitches. The objective of the book is to introduce researchers and graduate course students who are interested in "photon-working switches" not only to the fundamentals but also to the latest research being carried out in this field. Light can reach a target substrate without any physical contact to deliver energy. The energy can induce changes in the structure of the molecules included in the substrate so that its properties and functions are made switchable by light irradiation. When a substrate is able to revert to its original state, this system can be regarded as a "photon-working switch". The terms "photon-working switches" or "photoswitches" are almost equivalent in meaning to "photochromism"; however, they focus on the "switching of functions" of chemical species rather than their "reversible transformation". Most of the authors of this volume are members of PHENICS, an international research group on organic molecular photoswitches composed of research institutions from France, Japan, Russia, China and Germany. Since its inception in 2008, PHENICS has promoted active research to develop the field. This book commemorates the group's eighth year of collaborative research.

Download or read book Chromic Phenomena 3rd Edition written by Peter Bamfield and published by Royal Society of Chemistry. This book was released on 2018-08-24 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chromic or colour related phenomena are produced in response to a chemical or physical stimulus. This new edition will update the information on all those areas where chemicals or materials interact with light to produce colour, a colour change, or luminescence especially in the imaging, analysis, lighting and display areas. The book has been restructured to show greater emphasis on applications where 'coloured' compounds are used to transfer energy or manipulate light in some way therefore reducing the details on classical dyes and pigments. In the past eight years, since the previous edition, there has been a remarkable increase in the number of papers and reviews being produced reflecting the growth of interest in this area. This ongoing research interest is matched by a large number of new technological applications gaining commercial value covering e.g. biomedical areas, energy, data storage, physical colour, bio-inspired materials and photonics. This book appeals to industrial chemists, professionals, postgraduates and as high level recommended reading for colour technology courses.

Download or read book Semiconductor Integrated Optics for Switching Light written by Charlie Ironside and published by Morgan & Claypool Publishers. This book was released on 2017-09-12 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the technology of switching or modulating light in semiconductor optical waveguides. Currently a key function for optical communications systems is the conversion of data from an electrical signal to an optical signal for transmission in very low loss optical fibres and the converse process of optical to electrical conversion the O/E/O data conversion. This conversion between electronic and photonic signals imposes an energy consumption overhead on optical communication systems. So many research workers have been attracted to ultrafast all-optical switching of data in different formats. As a way of introduction to all-optical switching in semiconductor waveguides the book covers the electro-optic effect, electroabsorption and electrorefraction; effects that can be used in semiconductor optical modulation devices. But the book focuses on all-optical switching using second and third order optical nonlinearities in AlGaAs optical waveguides. It covers a variety of device configurations including integrated nonlinear couplers and Mach-Zehnder interferometers. Further, it provides design software in suit of Mathematica notebooks that can be used to explore the device design.

Download or read book Active Multiplexing of Spectrally Engineered Heralded Single Photons in an Integrated Fibre Architecture written by Robert J.A. Francis-Jones and published by Springer. This book was released on 2017-08-14 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This clearly written thesis discusses the development of a highly innovative single-photon source that uses active optical switching, known as multiplexing, to increase the probability of delivering photons into a single mode. Improving single-photon sources is critical in advancing the state of the art in photonic quantum technologies for information processing and communications.

Download or read book Quantum Dots for Quantum Information Technologies written by Peter Michler and published by Springer. This book was released on 2017-06-01 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the most recent developments in quantum dot spin physics and the generation of deterministic superior non-classical light states with quantum dots. In particular, it addresses single quantum dot spin manipulation, spin-photon entanglement and the generation of single-photon and entangled photon pair states with nearly ideal properties. The role of semiconductor microcavities, nanophotonic interfaces as well as quantum photonic integrated circuits is emphasized. The latest theoretical and experimental studies of phonon-dressed light matter interaction, single-dot lasing and resonance fluorescence in QD cavity systems are also provided. The book is written by the leading experts in the field.

Download or read book Single-Photon Generation and Detection written by Ivo Pietro Degiovanni and published by Elsevier Inc. Chapters. This book was released on 2013-11-29 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter presents an overview of efforts to improve photon-counting detection systems through the use of hybrid detection techniques such as spatial- and time-multiplexing of conventional detectors, and frequency up-conversion. It reviews the basic operation for these methods and illustrates their utility in a number of applications showing new or improved capabilities compared with conventional methods.
