Book Description
Sol-gel processing is a low temperature, low cost wet chemistry route to a range of different materials, particularly glassy and ceramic oxides, including nanoparticles and powders, fibers, thin films and membranes, or monoliths and composites. Thin films and coatings represent by far the most important category of sol-gel derived products with optical, electronic and magnetic functionalities, for example photoresist and dielectric spin-on-glass layers, flat screen displays, anti-reflection, conducting and magnetic disk coatings, as well as photochromic, electrochromic and photovoltaic coatings. Sol-gel derived materials are homogeneous at the molecular level and are a good example of a bottom-up approach to materials synthesis. There is increasing need of new optical and photonic materials with improved performance, where molecular level homogeneity and easy fabrication in film form may be especially convenient, highlighting a decisive advantage of sol-gel over other more established technologies to obtain graded index optical components, solar control coatings, phosphors, glass ceramics or multilayer photonic structures. There is no book available yet which focuses in particular on optical and photonic sol-gel derived materials. This is what makes this book unique at this point for those especially or exclusively interested in optical and photonic functional materials and applications. This book represents an important tool to update scientists and engineers with recent advances in the rapidly evolving field of optical and photonic materials, components and devices. Our target audience are those working in materials science, physics, engineering and chemistry disciplines, in particular academics and researchers working in advanced optical/photonic processing technologies, research and development engineers in high technology industries and research project leaders. This book will also be an essential tool for graduate students pursuing a PhD or even a Master's degree. - Reviews wide range of sol-gel derived coatings including reflective and anti-reflective, self-cleaning, and electrochromic - Discusses latest advances in sol-gel derived photonic crystals including one dimensional, two dimensional, and three dimensional structures - Addresses key applications in solid state lighting, solar cells, sensors, fiber optics, and magneto-optical devices

Book Description
Advances in photonic materials are critical to the progress of photonic devices and optical systems. Even though a variety of materials, e.g. semiconductors, oxide based glasses, and polymers exist which are being used for numerous applications, there is a growing need to develop and find new materials in order to push the limits we are bound by with conventional materials, in pursuit of higher performance, higher levels of integration and lower cost. In this realm, new material development has had a considerable impact, as it is the material properties (optical, thermal, mechanical, electrical, ...) in addition to their processing and compatibilities with standard processes that enable us the creation of entirely new devices or improve the performance of currently available optical devices. In this dissertation, I will demonstrate the application of two new materials for novel photonic components. In the first part of the dissertation, I discuss how a hybrid approach to the silicon photonics platform can reduce thermal sensitivity using sol-gel based inorganic-organic hybrid materials. The approach is to design the optical waveguide so that it maintains its performance in a passive manner in response to environmental temperature variations and, thus, does not need external temperature control resulting in reduced electrical power consumption. Sol-gel materials are well-known, but they haven’t been exploited like polymers and titanium dioxide to be cladding layers to enable athermal silicon waveguides. In this work I show their advantages with respect to previous materials that were employed for athermal microring resonators. I studied the thermal curing parameters of the sol-gel and its effect on thermal wavelength shift of the microring resonance. With this method, I was able to achieve a thermal shift down to -6.8 pm/°C for transverse electric (TE) polarization, as well as thermal shifts below 1 pm/°C for transverse magnetic (TM) polarization in the C band under different curing conditions, all while preserving high Q resonator performance. The results and methodology described opens a new and more manufacturable approach to attain athermal silicon photonic devices. In the second part of the dissertation, I introduced a new, sulfur rich, low cost copolymer material developed by our colleagues in the chemistry department. This copolymer has unique properties that conventional optical polymers, such as polymethylmethacrylate and polycarbonate, lack, while also having low cost. I demonstrated that these polymers have very good processing capabilities, being easily moldable to make free space optical elements and solution processable for use in integrated optics. I studied their linear and nonlinear optical properties, finding them to possess high refractive indices and transparencies over a wide range from 550 nm to 6 μm, except for a small region of absorption from 3-3.3 μm. Finally, I demonstrated that these new copolymers are suitable and economical alternative for shortwave and midwave infrared optics (SWIR and MWIR, respectively).

Book Description
Since Dr. Disiich of Germany prepared a glass lens by the sol-gel method around 1970, sol-gel science and technology has continued to develop. Since then this field has seen remarkable technical developments as well as a broadening of the applications of sol-gel science and technology. There is a growing need for a comprehensive reference that treats both the fundamentals and the applications, and this is the aim of "Handbook of Sol-Gel Science and Technology."The primary purpose of sol-gel science and technology is to produce materials, active and non-active including optical, electronic, chemical, sensor, bio- and structural materials. This means that sol-gel science and technology is related to all kinds of manufacturing industries. Thus Volume 1, "Sol-Gel Processing," is devoted to general aspects of processing. Newly developed materials such as organic-inorganic hybrids, photonic crystals, ferroelectric coatings, photocatalysts will be covered. Topics in this volume include: Volume 2, "Characterization of Sol-Gel Materials and Products, "highlights the important fact that useful materials are only produced when characterization is tied to processing. Furthermore, characterization is essential to the understanding of nanostructured materials, and sol-gel technology is a most important technology in this new field. Since nanomaterials display their functional property based on their nano- and micro-structure, "characterization" is very important. Topics found in Volume 2 include: Sol-gel technology is a versatile technology, making it possible to produce a wide variety of materials and to provide existing substances with novel properties. This technology was applied to producingnovel materials, for example organic-inorganic hybrids, which are quite difficult to make by other fabricating techniques, and it was also applied to producing materials based on high temperature superconducting oxides. "Applications of Sol-Gel Technology," (Volume 3), will cover applications such as:

Book Description
Sol-Gel processing methods, first used historically for decorative and constructional materials, were extensively developed in the last century for applications such as glasses, ceramics, catalysts, coatings, composites and fibres. Today they are reaching their full potential, enabling the preparation of new generations of advanced materials not easily accessible by other methods yet using mild, low-energy conditions. The topic is therefore increasingly included in advanced undergraduate, MSc and PhD programmes in the areas of chemistry, physics and materials science. This concise introductory text, written at the advanced undergraduate/first-year postgraduate level, is also suitable as an introduction to the development, mechanisms, chemistry, characterisation methods and applications of the technique. It provides readers with an extensive yet concise grounding in the theory of each area of the subject and details the real and potential applications and the future prospects of sol-gel chemistry.
