Book Description

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.

Book Description

The Terahertz Band (0.1-10 THz) is envisioned as a key a wireless technology that will enable Terabit-per-second data rate, which is expected to become a reality within the next five years. One of the main problems of this technology is the lack of compact high-power signal sources in order to overcome the very high path loss. Novel plasmonic devices based on nanomaterials such as graphene are a new promising alternative capable to efficiently operate at THz frequencies. In this thesis, the performance of a graphene-based plasmonic device for on-chip direct generation, modulation, and detection of THz signals is proposed, modeled and simulated using a finite-difference-based multi-physics simulation platform, which can handle both hydrodynamic model equations and Maxwell's equations. The device is based on a gated High Electron Mobility Transistor (HEMT) with graphene as the 2DEG channel, where a THz plasmonic signal is generated by implementing an asymmetric boundary condition at the source and drain. Moreover, this setup offers the possibility to modulate the generated signal by changing the applied current density.

Book Description

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.

Book Description

In this thesis, we focus on graphene-based surface plasmon-polaritons at terahertz frequencies and their possible applications. The primary motivation is to efficiently couple free-space terahertz radiation into an ultra-compact and low-loss waveguide. Characteristics of surface plasmon-polaritons on monolayer and double-layer graphene are first re-derived and reviewed. Then we propose two novel waveguide structures: graphene-metal structure and graphene-wrapped fibers. Possible modes that can be supported by the structures are analyzed and how to excite them is addressed. Also, promising applications are briefly described. Our work reveals that graphene-metal structure is a good starting point for exploration of both new physics and innovative devices, and that graphene-wrapped fibers can also be of substantial interest as the quality of graphene is improved.
