The use of lithium niobate in signal filtering in TV sets and video cassette recorders is well established and it is finding increased application in optoelectronic modulation devices in DWDM (dense wavelength division multiplexing) fibre optic systems. This fully illustrated volume brings electronic engineers, materials scientists and physicists up to date by enlisting the expertise of active researchers and presenting their considered reviews.
This book covers new research on LiNbO3 including current studies on intrinsic and extrinsic point defects and the contribution of intrinsic defects to photoinduced charge transport. Applications of this material are also discussed.
With the use of ferroelectric materials in memory devices and the need for high-speed integrated optics devices, interest in ferroelectric thin films continues to grow. With their remarkable properties, such as energy nonvolatility, fast switching, radiative stability and unique optoacoustic and optoelectronic properties, Lithium Niobate-Based Heterostructures: Synthesis, properties and electron phenomena discusses why lithium niobate (LiNbO3) is one of the most promising of all ferroelectric materials. Based on years of study, this book presents the systematic characterization of substructure and electronic properties of a heterosystem formed in the deposition process of lithium niobate films onto the surface of silicon wafers.
Lithium niobate crystals have a number of unique properties. Lithium niobate is at the same time a ferroelectric, piezoelectric, pyroelectric, and has high nonlinearly optical and electro-optical coefficients and photorefractive sensitivity. These properties enable these crystals to be used widely in optical and acoustic devices, and photorefractive sensitivity, enhanced by doping with transitional metals, offers new possibilities of using lithium niobate as a recording holographic medium. These properties are determined by the crystal structure of lithium niobate sensitive to physical and chemical effects. Special attention is given in the book to physico-chemical features of technology, disruption of stoichiometry in these crystals and detection of this disruption by physical methods. At the same time, the ideas and methods proposed in the book can be used in technology of other crystals.
Confinement and manipulation of photons using microcavities have triggered intense research interest in both basic and applied physics for more than a decade. Prominent examples are whispering gallery microcavities which confine photons by means of continuous total internal reflection along a curved and smooth surface. The long photon lifetime, strong field confinement, and in-plane emission characteristics make them promising candidates for enhancing light-matter interactions on a chip. In this book, we will introduce different ultra-high-Q whispering gallery microcavities, and focus on their applications in enhancing light-matter interaction, such as ultralow-threshold microlasing, highly sensitive optical biosensing, nonlinear optics, cavity quantum electrodynamics and cavity optomechanics.
This new resource presents the concepts, technologies, and design techniques for devices based on the electro-optic effect in lithium niobate. It bridges from the theory of photonics and electro-optics, to the practice of electro-optic device design and application. There is an emphasis on practical analysis using modern modeling tools. The book explains the fundamental physics of the electro-optic effect, classes of electro-optic materials, electro-optic properties of lithium niobate, and the physics and uses of ferroelectric domain inversion. Readers are also provided with the principles of operation, performance measures, and design considerations for the most common types of electro-optic devices: beam deflectors, intensity and phase modulators, including quasi-phased matched devices.
This book is a collection of research papers that describe some of the latest research on lithium niobate, which is an important material with many technological applications. The papers fall into three sections, which respectively consider the relationship between photorefractive properties and the defect structure of lithium niobate, powder preparation using a wet chemistry method and high-energy ball-milling technique, and finally the investigation of the domain structures, stability and conduction, and applications in waveguide devices.

This book presents the basic physical properties, structure, fabrication methods and applications of ferroelectric materials. These are widely used in various devices, such as piezoelectric/electrostrictive transducers and actuators, pyroelectric infrared detectors, optical integrated circuits, optical data storage, display devices, etc. The ferroelectric materials described in this book include a relatively complete list of practical and promising ferroelectric single crystals, bulk ceramics and thin films. Included are perovskite-type, lithium niobate, tungsten-bronze-type, water-soluable crystals and other inorganic materials, as well as organic ferroelectrics (polymers, liquid crystals, and composites). Basic concepts, principles and methods for the physical property characteristics of ferroelectric materials are introduced in the first two chapters for those readers new to the subject of ferroelectricity. Not only professional researchers and engineers but also students and other readers who have limited physical knowledge and an interest in ferroelectrics, will welcome this book.
