Plasmonic Nanoguides and Circuits

Modern communication systems dealing with huge amounts of data at ever increasing speed try to utilize the best aspects of electronic and optical circuits. Electronic circuits are tiny but their operation speed is limited, whereas optical circuits are extremely fast but their sizes are limited by diffraction. Waveguide components utilizing surface plasmon (SP) modes were found to combine huge optical bandwidth and compactness of electronics, and plasmonics thereby became considered as the next chip-scale technology. In this book, we concentrate on the SP waveguide configurations ensuring nanoscale confinement and review the current status of this rapidly emerging field, considering different configurations being developed for nanoscale plasmonic guides and circuits. Both fundamental physics and application aspects of plasmonics are reviewed in detail by world-leading experts.
