Lithium Niobate Crystals by I︠U︡riĭ Sergeevich Kuzʹminov Pdf
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.

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 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.
Photonic integrated circuit (PIC) technology holds great potential for breaking through the bottlenecks in current photonic and optoelectronic networks. Recently, a revolution has been witnessed in the field of lithium niobate (LN) photonics. Over the past decade, nanoscale LN waveguides with a propagation loss of ~0.01 dB and a radius of curvature on the level of ~100 μm have been demonstrated. The revolution mainly benefits from two technological advancements, the maturity of lithium-niobate-on-insulator (LNOI) technology and the innovation of nanofabrication approaches of high-quality LNOI photonic structures. Using low-loss waveguides and high-quality-factor (high-Q) microresonators produced on the LNOI platform as building blocks, various integrated photonic devices have been demonstrated with unprecedented performances. The breakthroughs have reshaped the landscape of the LN industry. This is the first monograph on LN nanophotonics enabled by the LNOI platform. It comprehensively reviews the development of fabrication technology, investigations on nonlinear optical processes, and demonstrations of electro-optical devices, as well as applications in quantum light sources, spectroscopy, sensing, and microwave-to-optical wave conversion. The book begins with an overview of the technological evolution of PICs, justifying the motivation for developing LNOI photonics. The next four chapters focus on LNOI photonics. The book concludes with a summary of the milestone achievements discussed in these chapters and provides a future perspective of this area of research.
Electron-phonon Interactions in Low-dimensional Structures by Lawrence John Challis Pdf
The study of electrons and holes confined to two, one and even zero dimensions has uncovered a rich variety of new physics and applications. This book describes the interaction between these confined carriers and the optic and acoustic phonons within and around the confined regions. Phonons provide the principal channel of energy transfer between the carriers and their surroundings and also the main restriction to their room temperature mobility. But they have many other roles; they provide for example an essential feature of the operation of the quantum cascade laser. Since their moment at the relevant energies are well matched to those of electrons, they can also be used to probe electronic properties such as the confinement width of 2D electron gases and the dispersion curve of quasiparticles in the fractional quantum Hall effect. The book describes both the physics of the electron-phonon interaction in the different confined systems and the experimental and theoretical techniques that have been used in its investigation. The experimental methods include optical and transport techniques as well techniques in which phonons are used as the experimental probe. The aim of the book is to provide an up-to-date review of the physics and its significance in device performance. It is also written to be explanatory and accessible to graduate students and others new to the field.

Synthesis and Modification of Nanostructured Thin Films by Ion N. Mihailescu Pdf
The Special Issue “Synthesis and Modification of Nanostructured Thin Films” highlights the recent progress in thin film synthesis/modification and characterization. New methods are reviewed for the synthesis and/or modification of thin films based on laser, magnetron, chemical, and other techniques. The obtained thin nanostructures are characterized by complex and complementary techniques. We think that most of proposed methods can be directly applied in production, but some others still need further elaboration for long-term prospective applications in lasers, optics, materials, electronics, informatics, telecommunications, biology, medicine, and probably many other domains. The Guest Editor and the MDPI staff are therefore pleased to offer this Special Issue to interested readers, including graduate and PhD students as well as postdoctoral researchers, but also to the entire community interested in the field of nanomaterials. We share the conviction that this can serve as a useful tool for updating the literature, but also to aid in the conception of new production and/or research programs. There is plenty of room for further dedicated R&D advances based on new instruments and materials under development.

Photorefractive Optoelectronic Tweezers and Their Applications by Michael Esseling Pdf
In the never-ending quest for miniaturization, optically controlled particle trapping has opened up new possibilities for handling microscopic matter non-invasively. This thesis presents the application of photorefractive crystals as active substrate materials for optoelectronic tweezers. In these tweezers, flexible optical patterns are transformed into electrical forces by a photoconductive material, making it possible to handle matter with very high forces and high throughput. Potential substrate materials’ properties are investigated and ways to tune their figures-of-merit are demonstrated. A large part of the thesis is devoted to potential applications in the field of optofluidics, where photorefractive optoelectronic tweezers are used to trap, sort and guide droplets or particles in microfluidic channels, or to shape liquid polymers into optical elements prior to their solidification. Furthermore, a new surface discharge model is employed to discuss the experimental conditions needed for photorefractive optoelectronic tweezers.
