Near Field Optics And Nanoscopy

This book contains the most recent information on optical nanoscopy. Far-Field and Near-Field properties on e.m. waves are presented which illustrate how optical images can be obtained from sub-micron objects. Scanning Probe techniques and computer processing are covered here. An explanation is given on how propagating photons or evanescent waves can behave over distances shorter than the wavelength, taking into account the presence of small objects. Quantum tunneling of photons is explained comparatively with the electron mechanism. Technical details are given on photon tunneling microscopes. Typical results already obtained with these techniques are also described.

Near-field optics, dealing with the interaction between optical field and matter in the nanometric region, has become an interdisciplinary field spaning physics, chemistry, materials science, electrical engineering and high density data storage. This book reflects the recent status of this rapidly growing field. It discusses the basic theories, instrumentation, novel probes, theoretical simulations, and the application of near-field optics to the fields of condensed matter physics, new materials, information storage, atom photonics, etc. It provides an overview of the research on near-field optics in the 1990s.

"This groundbreaking book focuses on near-field microscopy which has opened up optical processes at the nanoscale for direct inspection. Further, it explores the emerging area of nano-optics which promises to make possible optical microscopy with true nanometer resolution. This frontline resource helps you achieve high resolution optical imaging of biological species and functional materials. You also find guidance in the imaging of optical device operation and new nanophotonics functionalities"--EBL.

Covers not only near-field optical microscopy but also wider fields such as local spectroscopy, nano-scale optical processing, quantum near-field optics, and atom manipulation.

Scanning near-field optical microscopy (SNOM, also known as NSOM) is a new local probe technique with a resolving power of 10--50 nm. Not being limited by diffraction, near-field optics (NFO) opens new perspectives for optical characterization and the understanding of optical phenomena, in particular in biology, microelectronics and materials science. SNOM, after first demonstrations in '83/'84, has undergone a rapid development in the past two to four years. The increased interest has been largely stimulated by the wealth of optical properties that can be investigated and the growing importance of characterization on the nanometer scale in general. Examples include the use of fluorescence, birefrigence and plasmon effects for applications in particular in biology, microelectronics and materials science, to name just a few. This volume emerged from the first international meeting devoted exclusively to NFO, and comprises a complete survey of the 1992 activities in the field, in particular the variety of instrumental techniques that are currently being explored, the demonstration of the imaging capabilities as well as theoretical interpretations - a highly nontrivial task. The comprehensive collection of papers devoted to these and related subjects make the book a valuable tool for anybody interested in near-field optics.

This book builds a narrative on the near-field optical and spectroscopic studies with an emphasis on plasmonic- and photonic-assisted nano-optics as a tool for superlensing. Deliberations on near-field studies using confined light in various applications are included along with their commercial implications. Single-molecule detection utilizing efficient surface-enhanced Raman scattering phenomenon in the far-field and plasmonic tip-enhanced Raman scattering studies in the near-field measurements for fast analysis up to trace level is discussed. Features: Covers the broad area of nano-optical spectroscopy from the perspective of putting the concepts and innovations in the field to use. Discusses entire spectra of near-field optics and spectroscopy using light. Explores gas/chemical sensing using surface plasmon resonance (SPR) in the Kretschmann configuration. Includes dielectric nano-photonics and optical confinement. Studies phonon behaviour using confined light for the analysis of chemical, biological, and other materials. This book is aimed at graduate students and researchers in material science, analytical chemistry, nanotechnology, and electrical engineering.

Intrinsic features of the optical near field open a new frontier in optical science and technology by finally overcoming the diffraction limit to reach nanometric dimensions. But this book goes beyond near-field optical microscopy to cover local spectroscopy, nanoscale optical processing and storage, quantum near-field optics, and atom manipulation. Near-Field Nano/Atom Optics and Technology provides the first complete and systematically compiled account of the science and technology required to generate the near field, and features applications including imaging of biological specimens and diagnostics for semiconductor nanomaterials and devices. This monograph will be invaluable to researchers who want to implement near-field technology in their own work, and it can also be used as a textbook for graduate or undergraduate students.
