Graphene Based Terahertz Electronics And Plasmonics

Graphene demonstrates interesting electrical, optical, and optoelectronic properties. A number of other one-atom-thick material structures have been discovered and studied. Industrially applicable technologies for these structures are currently under active development. In spite of enormous research in the area of devices based on graphene, the number of extensive review publications on THz devices based on graphene is small. This review volume would fill the gap. Researchers and engineers working in the fields of electronics and plasmonics can use it to understand the influence of plasmonics on device performance. The book can be also be used as a required text for doctorate courses and as a supplementary material for postgraduate courses. The material presented in the book is reviewed in detail in Chapter 1. Chapter 2 discusses the electronic and plasmonic properties of graphene and heterostructures based on graphene for all devices. Chapters 3–7 focus on the concepts of detectors and emitters with a special emphasis on plasmonic enhancement of those devices as well as on population inversion and lasing.

There are growing advantages to the use of graphene-based nanophotonics in communication, sensing, security, safety, spectroscopy, manufacturing, biomedicine, agriculture, imaging, and other fields. These advantages, as well as the numerous challenges associated with this technology and proposed solutions to these challenges, are summarized in this book. The key objective of the book is to serve as a single-source reference for the rapidly expanding application aspects of the technology of graphene-based nanophotonics, as well as the number of modules required for their successful implementation. This book seeks to give readers a comprehensive understanding of several elements of graphene-based nanophotonics, such as emerging application areas, the design and modelling of sensors, absorbers, optical fiber, encoders, etc. A complete view of the progress and breakthroughs in novel materials for sensing, detecting and encoding technology is presented. The book also emphasizes the consequences of THz signals on human health, as well as the environmental components of THz. This book will be of tremendous value for those with an interest in electronic engineering, particularly those keeping an eye on this emerging technology.

Graphene is a single-layer crystal of carbon, the thinnest two-dimensional material. It has unique electronic and photonic properties.

Graphene has been hailed as a rising star in photonics and optoelectronics. The wonderful optical properties of graphene make possible the multiple functions of signal emission, transmission, modulation, and detection to be realized in one material. This book compiles and details cutting-edge research in graphene photonics, plasmonics, and broadband optoelectronic devices. Particularly, it emphasizes the ability to integrate graphene photonics onto the silicon platform to afford broadband operation in light routing and amplification, which involves components such as the polarizer, the modulator, and the photodetector. It also includes other functions such as a saturable absorber and an optical limiter. The book provides a comprehensive overview of the interrelationship between the operation of these conceptually new photonic devices and the fundamental physics of graphene involved in the interactions between graphene and light.

This book is meant as an introduction to graphene plasmonics and aims at the advanced undergraduate and graduate students entering the field of plasmonics in graphene. In it different theoretical methods are introduced, starting with an elementary description of graphene plasmonics and evolving towards more advanced topics. This book is essentially self-contained and brings together a number of different topics about the field that are scattered in the vast literature. The text is composed of eleven chapters and of a set of detailed appendices. It can be read in two different ways: Reading only the chapters to get acquainted with the field of plasmonics in graphene or reading the chapters and studying the appendices to get a working knowledge of the topic. The study of the material in this book will bring the students to the forefront of the research in this field.
