A book on nano-optics

'Optical antennas' has been written by leading experts in electrical engineering, nano-optics and nano-photonics, physical chemistry and nanofabrication, and has been edited by Mario Agio, researcher at Cnr-National Institute of Optics (Ino) and Andrea Alù, University of Texas at Austin.

Each contribution has been selected to shape a complete book structured in a coherent manner, with the goal of guiding the reader through the different languages and diverse approaches in design, fabrication, characterization and applications of optical antennas. The aim is not only to provide a consistent and well-organized survey of recent advances in the field, but also to help setting a common playground for exciting future work in the area. The book wishes to become a fundamental resource, not only for experienced researchers in the areas of nano-optics, but also to the curious scientists, post-docs and graduate students who want to get closer to this exciting field of research.

Recent years have witnessed a tremendous progress in nanofabrication, as well as in the theoretical and experimental understanding of light-matter interaction at the nanoscale. The field of nano-optics has thrived during these times and one of the most exciting related advances in this area has been the concept, design and application of optical antennas, or nanoantennas. Starting within the onset of field-enhanced spectroscopy and near-field optics, optical antennas have rapidly evolved into a sophisticated tool to enhance and direct spontaneous emission from quantum light sources, boost light-matter interaction and optical nonlinearities at the nanoscale, as well as implement realistic optical communication links. The amount of research activity on optical antennas has grown very rapidly in the last few years, and currently spans a broad range of areas, including optics, physics, chemistry, electrical engineering, biology, and medicine, to cite a few.

The rapid progress and inherent multidisciplinarity of nanoantennas have produced a situation in which the involved research communities do not necessarily speak the same language. If electrical engineers have an established formalism based on circuit and radiation concepts developed over decades of antenna engineering and design, in optics, physics or chemistry many of the same phenomena are described in very different terms. It is exactly this interdisciplinarity, however, that may lead to groundbreaking findings and applications in a variety of fields of modern science.

Fundamental concepts and functionalities relevant to optical antennas are explained, together with key principles for optical antenna modelling, design and characterization, in order to provide researchers and graduate students in engineering, optics and photonics, physics and chemistry an interdisciplinary view.

The volume will be available from March 2013.
