The book addresses many problems of ion exchange processes in LiNbO3, LiTaO3 and KTiOPO4 ferroelectrics and II-VI semiconductor single crystals for integrated optics applications. The authors start with the fundamentals of ion exchange processes in solids (Chapter 1). Chapter 1 can be considered also as an enlarged introduction to the book. Starting with Chapter 2, the general properties of LiNbO3 and LiTaO3 crystals, the methods used to study optical waveguides in these crystals as well as advanced preparation methods of optical waveguides are reviewed. Chapters 3, 4 and 5 are devoted to recent progress in the ion exchange processes in LiNbO3, LiTaO3 and KTiOPO4 crystals, respectively, and Chapter 6 summarizes the main applications of ion-exchanged waveguides in modern integrated optics. Finally, Chapter 7 deals with recently established ion exchange processes in II-VI semiconductors.
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.
Although it took some time to establish the word, photonics is both widely accepted and used throughout the world and a major area of activity concerns nonlinear materials. In these the nonlinearity mainly arises from second-order or third-order nonlinear optical processes. A restriction is that second-order processes only occur in media that do not possess a centre of symmetry. Optical fibres, on the other hand, being made of silica glass, created by fusing SiO molecules, are made of material with a centre of z symmetry, so the bulk of all processes are governed by third-order nonlinearity. Indeed, optical fibre nonlinearities have been extensively studied for the last thirty years and can ...
This review volume presents new developments in the preparation, physical characterization and applications of insulating materials for Optoelectronics. Insulators occupy a leading position as laser and optical amplifier hosts, electrooptic and acoustooptic modulators, frequency doublers and optical parametric oscillators, photorefractive devices and radiator detectors. These applications rely heavily on the development of advanced techniques for the preparation of both bulk and waveguide structures, the adequate knowledge of the microscopic behaviour defects, impurities and a thorough understanding of their response to electromagnetic fields. All these topics relating basic physicochemical aspects and applied performance are authoritatively discussed in the book.

Doped by isovalent or heterovalent foreign impurities (F), II-VI semiconductor compounds enable control of optical and electronic properties, making them ideal in detectors, solar cells, and other precise device applications. For the reproducible manufacturing of the doped materials with predicted and desired properties, manufacturing technologists
This volumes presents recent results in the physics and chemistry of nanostructures, nano-technology, and nano-size optical and electron devices. The level of understanding of the nanoworld is apparent from the book.
The aim of this 3-volume reference is to present accurate, reliable and up-to-date information on the physical properties of group IV elemental semiconductors (Vol. 1), III-V compound semiconductors (Vol. 2) and II-VI semiconductors (Vol. 3). The data on the physical properties of each material are organized in the same way throughout these volumes to facilitate searching for information. The physical properties considered in these volumes can be classified into 12 groups: structural properties; -thermal properties; -elastic properties; -phonons and lattice vibronic properties; -collective effects and related properties; -energy-band structure: energy-band gaps; -energy-band structure: electron and hole effective mass; -electronic deformation potential; -electron affinity and Schottky barrier height; -optical properties; -elastooptic, electrooptic and nonlinear optical properties; and, -carrier transport properties. An extensive bibliography is included for those who wish to find additional information.
