Book Description
This book outlines physically intuitive concepts and theories for students, engineers, and scientists who will be engaged in research in nanophotonics and atom photonics. The main topic is the optical near ?eld, i.e., the thin ?lm of light that is localized on the surface of a nanometric material. In the early 1980s, one of the authors (M. Ohtsu) started his pioneering research on optical near ?elds because he judged that nanometer-sized light would be required to shift the paradigm of optical science and technology. This ?eld of research did not exist previously, and was not compatible with trends in opticalscienceandtechnology.However,hewasencouragedbytheknowledge that scientists in other countries started similar research in the mid 1980s. In the 1990s, optical technology progressed very rapidly and the p- tonics industry developed, but further progress became di?cult due to the fundamental limit of light known as the di?raction limit. However, there was a growing awareness among scientists and engineers that this limit can be overcome using optical near ?elds. Since a drastic paradigm shift in the c- cepts of optics is required to understand the intrinsic nature of optical near ?elds, the demand for a textbook on this subject has increased. The present book aims to meet this demand.

Book Description
Conventional optical science and technology have been restricted by the diffraction limit from reducing the sizes of optical and photoruc devices to nanometric dimensions. Thus, the size of optical integrated circuits has been incompatible with that of their counterpart, integrated electronic circuits, which have much smaller dimensions. This book provides potential ideas and methods to overcome this difficulty. Near-field optics has developed very rapidly from around the middle 1980s after preliminary trials in the microwave frequency region, as proposed as early as 1928. At the early stages of this development, most technical efforts were devoted to realizing super-high-resolution optical microscopy beyond the diffraction limit. However, the possibility of exploiting the optical near-field, phenomenon of quasistatic electromagnetic interaction at subwavelength distances between nanometric particles has opened new ways to nanometric optical science and technology, and many applications to nanometric fabrication and manipulation have been proposed and implemented. Building on this historical background, this book describes recent progress in near-field optical science and technology, mainly using research of the author's groups. The title of this book, Near-Field Nano-Optics-From Basic Principles to Nano-Fabrication and Nano-Photonics, implies capabilities of the optical near field not only for imaging/microscopy, but also for fabrication/manipulation/proc essing on a nanometric scale.

Book Description
The contributions in this volume were presented at a NATO Advanced Study Institute held in Erice, Italy, 4-19 July 2013. Many aspects of important research into nanophotonics, plasmonics, semiconductor materials and devices, instrumentation for bio sensing to name just a few, are covered in depth in this volume. The growing connection between optics and electronics, due to the increasing important role plaid by semiconductor materials and devices, find their expression in the term photonics, which also reflects the importance of the photon aspect of light in the description of the performance of several optical systems. Nano-structures have unique capabilities that allow the enhanced performance of processes of interest in optical and photonic devices. In particular these structures permit the nanoscale manipulation of photons, electrons and atoms; they represent a very hot topic of research and are relevant to many devices and applications. The various subjects bridge over the disciplines of physics, biology and chemistry, making this volume of interest to people working in these fields. The emphasis is on the principles behind each technique and on examining the full potential of each technique.

Book Description
The light-matter interaction in the near-field of high-Q resonators in SOI and SiN platforms is studied. The interactions of high-Q traveling-wave resonators with both resonant and non-resonant nanoparticles are studied and different applications based on this enhanced interactions in near-field such as high-resolution imaging of mode profile of high-Q resonators, label-free sensing, optical trapping, and SERS sensing are investigated. A near-field imaging system for the investigation of the near-field phenomena in the near-field of high-Q resonators is realized. A new technique for high-resolution imaging of the optical modes in high-Q resonators based on the near-field perturbation is developed that enables to achieve a very high resolution (

Book Description
Manipulation of light via subwavelength nanostructures is currently a subject of intense research interest, and is enabling the development of nanostructured photonic crystal, metamaterials and metasurfaces that provide a variety of new optical and electromagnetic functionalities, or that enable existing functionalities to be realized in new and often extremely compact form factors. This dissertation will include wide-angle wavelength-selective metasurface, omnidirectional enhancement in photovoltaic performance via subwavelength gradient anti-reflection coating, and applications of birefringent nanocylinders for single-molecule spectroscopy. In wide-angle wavelength-selective metasurface, high and broad reflectance (~95%) with low absorption (5%) are shown to be achieved with multilayer metasurface structures. These characteristics are shown to be independent of interlayer misalignment and defects within individual layers. Interactions between different metasurface layers due to Fabry-Perot resonance are also examined with analytical models and numerical simulations. Wavelength-selective focusing at optical wavelengths which is enabled by large-area nanosphere lithography on a flexible substrate is demonstrated. In omnidirectional enhancement in photovoltaic performance via subwavelength gradient anti-reflection coating, large-area "moth-eye" structure fabricated on a flexible substrate is shown to have high transmittance (85%) at large angle of incidences (>70°) and insensitivity to polarizations. Integration of the "moth-eye" anti-reflection coating together with nanostructured gradient A12O3/TiO2 on a GaAs solar cell shows significant improvements on external quantum efficiency (EQE) and short circuit current over all angle of incidences compared with conventional thin film anti-reflection coating. Detailed design, simulation, and fabrication of these nanostructured anti-reflection coating for reducing the discontinuity in refractive index profile will also be discussed. In application of birefringent nanocylinders for single-molecule spectroscopy, the design and fabrication method for large quantity of subwavelength birefringent nanoparticle are also discussed. These birefringent nanoparticles are shown to be stably trapped in an optical torque wrench setup, and enable observation of the dynamical response of a double-stranded DNA under torsional and extensional forces.
