About the book
The emerging nanophotonics from optics deals with the interaction of light with matters at the nanometer scales. It is the subject of many types of research and it covers many disciplines in science and engineering. As it is impossible to focus light at the nanometer scale using normal optical components, we need other techniques like surface plasmonic, metal optic and metal material to confine light at the sub-wavelength scale. Discovery of new phenomena based on quantum principle, development of a large number of nanostructures and nanodevices, the vast application of nanophotonics such as in optical communications, sensing, nanoscale optical sources, and in many other industries, have created a numerous opportunity of new research areas both on scientific fundamentals and technological applications. Nanophotonic structures and devices are the promising future technology that can revolutionize to name a few, the optical communications, energy conversion, integrated information systems, image processing, and sensors in all disciplines, particularly in nano-medicine. This book aims to present a collection of research articles on scientific fundamentals, fabrication, and characterization of devices based on nanophotonics, and on related fields such as plasmonics, and photonic crystals.
