Book Description
This book gives a solution to the problem of constructing lightwave paths in free spaces by proposing the concept of a Self-Organized Lightwave Network (SOLNET). This concept enables us to form self-aligned coupling optical waveguides automatically. SOLNETs are fabricated by self-focusing of lightwaves in photosensitive media, in which the refractive index increases upon light beam exposure, to realize the following functions: 1) Optical solder: Self-aligned optical couplings between misaligned devices with different core sizes 2) Three-dimensional optical wiring 3) Targeting lightwaves onto specific objects SOLNETs are expected to reduce the efforts to implement lightwaves into electronic systems and allow us to create new architectures, thus reducing costs and energy dissipation and improving overall system performance. SOLNETs are also expected to be applied to a wide range of fields where lightwaves are utilized, for example, solar energy conversion systems and biomedical technologies, especially photo-assisted cancer therapies. Readers will systematically learn concepts and features of SOLNETs, SOLNET performance predicted by computer simulations, experimental demonstrations for the proof of concepts, and expected applications. They will also be prepared for future challenges of the applications. This book is intended to be read by scientists, engineers, and graduate students who study advanced optoelectronic systems such as optical interconnects within computers and optical networking systems, and those who produce new ideas or strategies on lightwave-related subjects.

Book Description
Currently, light waves are ready to come into boxes of computers in high-performance computing systems like data centers and super computers to realize intra-box optical interconnects. For inter-box optical interconnects, light waves have successfully been introduced by OE modules, in which discrete bulk-chip OE/electronic devices are assembled using the flip-chip-bonding-based packaging technology. OE modules, however, are not applicable to intra-box optical interconnects, because intra-box interconnects involve “short line distances of the cm–mm order” and “large line counts of hundreds-thousands.” This causes optics excess, namely, excess components, materials, spaces, fabrication efforts for packaging, and design efforts. The optics excess raises sizes and costs of intra-box optical interconnects enormously when they are built using conventional OE modules. This book proposes the concept of self-organized 3D integrated optical interconnects and the strategy to reduce optics excess in intra-box optical interconnects.

Book Description
Among the many atomic/molecular assembling techniques used to develop artificial materials, molecular layer deposition (MLD) continues to receive special attention as the next-generation growth technique for organic thin-film materials used in photonics and electronics. Thin-Film Organic Photonics: Molecular Layer Deposition and Applications describes how photonic/electronic properties of thin films can be improved through MLD, which enables precise control of atomic and molecular arrangements to construct a wire network that achieves "three-dimensional growth". MLD facilitates dot-by-dot—or molecule-by-molecule—growth of polymer and molecular wires, and that enhanced level of control creates numerous application possibilities. Explores the wide range of MLD applications in solar energy and optics, as well as proposed uses in biomedical photonics This book addresses the prospects for artificial materials with atomic/molecular-level tailored structures, especially those featuring MLD and conjugated polymers with multiple quantum dots (MQDs), or polymer MQDs. In particular, the author focuses on the application of artificial organic thin films to: Photonics/electronics, particularly in optical interconnects used in computers Optical switching and solar energy conversion systems Bio/ medical photonics, such as photodynamic therapy Organic photonic materials, devices, and integration processes With its clear and concise presentation, this book demonstrates exactly how MLD enables electron wavefunction control, thereby improving material performance and generating new photonic/electronic phenomena.

Also various additional arguments on the advantages of the complex-valued neural networks enhancing the difference to real-valued neural networks are given in various sections. The book is useful for those beginning their studies, for instance, in adaptive signal processing for highly functional sensing and imaging, control in unknown and changing environment, robotics inspired by human neural systems, and brain-like information processing, as well as interdisciplinary studies to realize comfortable society. It is also helpful to those who carry out research and development regarding new products and services at companies. The author wrote this book hoping in particular that it provides the readers with meaningful hints to make good use of neural networks in fully practical applications. The book emphasizes basic ideas and ways of thinking. Why do we need to consider neural networks that deal with complex numbers? What advantages do the complex-valued neural networks have? What is the origin of the advantages? In what areas do they develop principal applications? This book answers these questions by describing details and examples, which will inspire the readers with new ideas.
