Photonics and electronics are endlessly converging into a single technology by exploiting the possibilities created by nanostructuring of materials and devices. It is expected that next-generation optoelectronic devices will show great improvements in terms of performance, flexibility, and energy consumption: the main limits of nanoelectronics will be overcome by using a photonics approach, while nanophotonics will become a mature technology, thanks to miniaturization strategies developed in microelectronics.Mastering such a complex subject requires a multidisciplinary approach and a solid knowledge of several topics. This book gives a broad overview of recent advances in several topical aspects of nanophotonics and nanoelectronics, keeping an eye on real applications of such technologies, and focuses on the possibilities created by advanced photon management strategies in optoelectronic devices.Starting from pure photonic systems, the book provides several examples in which the interaction between photonics and electronics is exploited to achieve faster, compact, and more efficient devices. A large number of figures and tables also support each chapter. This book constitutes a valuable resource for researchers, engineers, and professionals working on the development of optoelectronics.
