Book Description
Carbon nanotubes (CNTs), discovered in 1991, have been a subject of intensive research for a wide range of applications. In the past decades, although carbon nanotubes have undergone massive research, considering the success of silicon, it has, nonetheless, been difficult to appreciate the potential influence of carbon nanotubes in current technology. The main objective of this book is therefore to give a wide variety of possible applications of carbon nanotubes in many industries related to electron device technology. This should allow the user to better appreciate the potential of these innovating nanometer sized materials. Readers of this book should have a good background on electron devices and semiconductor device physics as this book presents excellent results on possible device applications of carbon nanotubes. This book begins with an analysis on fabrication techniques, followed by a study on current models, and it presents a significant amount of work on different devices and applications available to current technology.

Book Description
Because of their estimated ultra-high third-order nonlinearity, single-walled carbon nanotubes (CNTs) can be regarded as a potential new material for optical nonlinearity. The nonlinearity of CNTs is believed to originate from the inter-band transitions of the π-electrons, causing nonlinear polarization. In this respect, CNTs are similar to other organic optical materials that exhibit extremely high nonlinearity. CNT-based photonics devices offer several key advantages, including ultrafast response, robustness, tunability of wavelength, and compatibility to fibers. This chapter will describe the design and fabrication of CNT-based nonlinear photonic devices. CNTs with suitable diameters – and thus suitable operational wavelengths – are deposited or grown directly on different types of fibers or waveguides to ensure effective CNT–light interaction. Optical nonlinear effects including four-wave mixing (FWM), cross-phase modulation (XPM), and self-phase modulation (SPM) have been observed experimentally using fabricated CNT-based devices. Corresponding wavelength conversion and optical signal regeneration applications based on various nonlinear effects are discussed.

Book Description
Single-walled carbon nanotubes (SWCNTs) possessing outstanding linear and nonlinear optical properties are utilized as saturable absorbers (SAs) for passive mode-locking of different bulk solid-state lasers in a wide spectral range between 0.8 and 2μm. To overcome some of the limitations and drawbacks of currently available saturable absorbers, diverse carbon nanotubes and techniques for fabrication of single-walled carbon nanotube saturable absorbers (SWCNT-SAs) are investigated. In this chapter, we discuss various manufacturing procedures and essential characteristics of SWCNT-based passive mode-locking devices, and review recent demonstrations of passively mode-locked solid-state lasers employing different types of SWCNT-SAs.

Book Description
With their nano-scaled dimensions and extremely elevated optical nonlinearity, carbon nanostructures including single-walled carbon nanotubes and graphene have played a critical role in generating ultrafast optical pulses. The pulsation relies on passive mode-locking of the nanostructures, and has been enhanced by employing an evanescent field interaction scheme that guarantees the all-fiber high-power operation. Preparation schemes for pulsating devices have been evolving via the development of elegant processes such as optical deposition, electrospray, and aerosol deposition of carbon nanostructures, ensuring the dramatic increase of process efficiency. In this chapter, details of the technical achievements are addressed.

Book Description
Carbon nanotubes are exceptionally photostable fluorophores that emit in the near infrared range. Their novel optical properties make them particularly appealing for applications in biosensing. This chapter focuses on the state-of-the-art development of optical biosensors based on single-walled carbon nanotubes (SWCNTs); also, it draws attention to the basic photophysics of SWCNTs, optical-sensing mechanisms, and surface functionalization principles. The concerted efforts from the research community in the past decade have enabled the realization of several SWCNT-based optical biosensors that provide real-time, non-invasive analyte detection. We review the performance of these biosensors with regard to their sensitivity, selectivity and response time, and highlight the prospects and challenges of constructing biosensors for more advanced sensing applications.

Book Description
This volume presents the characterization methods involved with carbon nanotubes and carbon nanotube-based composites, with a more detailed look at computational mechanics approaches, namely the finite element method. Special emphasis is placed on studies that consider the extent to which imperfections in the structure of the nanomaterials affect their mechanical properties. These defects may include random distribution of fibers in the composite structure, as well as atom vacancies, perturbation and doping in the structure of individual carbon nanotubes.
