Surface Plasmon Nanophotonics

This book discusses a new class of photonic devices, known as surface plasmon nanophotonic structures. The book highlights several exciting new discoveries, while providing a clear discussion of the underlying physics, the nanofabrication issues, and the materials considerations involved in designing plasmonic devices with new functionality. Chapters written by the leaders in the field of plasmonics provide a solid background to each topic.

Current developments in optical technologies are being directed toward nanoscale devices with subwavelength dimensions, in which photons are manipulated on the nanoscale. Although light is clearly the fastest means to send information to and from the nanoscale, there is a fundamental incompatibility between light at the microscale and devices and processes at the nanoscale. Nanostructured metals which support surface plasmon modes can concentrate electromagnetic (EM) fields to a small fraction of a wavelength while enhancing local field strengths by several orders of magnitude. For this reason, plasmonic nanostructures can serve as optical couplers across the nano–micro interface: metal–dielectric and metal–semiconductor nanostructures can act as optical nanoantennae and enhance light matter coupling in nanoscale devices. This book describes how one can fully integrate plasmonic nanostructures into dielectric, semiconductor, and molecular photonic devices, for guiding photons across the nano–micro interface and for detecting molecules with unsurpassed sensitivity. ·Nanophotonics and Nanoplasmonics ·Metamaterials and negative-index materials ·Plasmon-enhanced sensing and spectroscopy ·Imaging and sensing on the nanoscale ·Metal Optics

The manipulation of light at the nanometer scale is highly pursued for both fundamental sciences and wide applications. The diffraction limit of light sets the limit for the smallest size of photonic devices to the scale of light wavelength. Fortunately, the peculiar properties of surface plasmons in metal nanostructures make it possible to squeeze light into nanoscale volumes and enable the manipulation of light and light–matter interactions beyond the diffraction limit. Studies on surface plasmons have led to the creation of a booming research field called plasmonics. Because of its various scientific and practical applications, plasmonics attracts researchers from different fields, making it a truly interdisciplinary subject. Nanophotonics: Manipulating Light with Plasmons starts with the general physics of surface plasmons and a brief introduction to the most prominent research topics, followed by a discussion of computational techniques for light scattering by small particles. Then, a few special topics are highlighted, including surfaceenhanced Raman scattering, optical nanoantennas, optical forces, plasmonic waveguides and circuits, and gain-assisted plasmon resonances and propagation. The book discusses the fundamental and representative properties of both localized surface plasmons and propagating surface plasmons. It explains various phenomena and mechanisms using elegant model systems with well-defined structures, is illustrated throughout with excellent figures, and contains an extensive list of references at the end of each chapter. It will help graduate-level students and researchers in nanophotonics, physics, chemistry, materials science, nanoscience and nanotechnology, and electrical and electronic engineering get a quick introduction to this field.

This second volume in the Handai Nanophotonics book series covers the area of Nanoplasmonics, a recent hot topic in the field of nanophotonics, impacting a diverse range of research disciplines from information technology and nanotechnology to the bio- and medical sciences. The interaction between photons and metal nanostructures leads to interesting and extraordinary scientific phenomena and produces new functions for nano materials and devices. Newly discovered physical phenomena include local mode of surface plasmon polariton excited in nanoparticles, hot spots on nano-rods and nano-cones, long range mode of surface plasmons excited on thin metal films, and dispersion relationship bandgaps of surface plasmons in periodic metal structures. These have been applied to, for example, single molecule detection and nano-imaging/spectroscopy, photon accumulation for lasing applications, optical nano-waveguides and nano-circuits. * interdisciplinary research text on the application of nanoplasmonics research and effects in devices for applications * bridges the gap between conventional photophysics & photochemistry and nanoscience * continuing the series that focuses on 'hot' areas of photochemistry, optics, material science and bioscience.
