Preface

The rapid developments in optical communication and integrated optics have expanded the interest in guided-wave optics, in which optical waveguide and optical fiber play a central role. The guided-wave photonics technology now plays a role in generating and processing information for sensing and other optical device applications in addition to its original application of transmitting information in fiber optic communication. The interaction between the propagating light with the optical fiber material is the foundation of the development of various applications such as optical amplifiers, fiber lasers, sensors, etc. The use and demand for optical fibers have grown in tandem with numerous new applications and this book aims to

Chapter 1 investigates the birefringence and polarization mode dispersion characteristics in various commercial single-mode fibers. It is shown that the frequency value has an important role in determining the effectiveness of the optical fiber performance and stability of power delivery applications. Chapter 2 describes the properties of a quantum signal in optical fiber and its application for quantum

Optical fiber sensors, another important application of optical fiber, have also experienced rapid development and attracted tremendous interest in recent years for various practical applications. Compared with the conventional electrical or other types of sensors, fiber sensors have many advantages including their immunity toward electromagnetic interference and their ability to be deployed in a corrosive and volatile environment. Optical fiber can not only transport information acquired by sensors at a high speed and in large volume but can also play the role of a sensing element itself. For instance, fiber Bragg grating (FBG) sensors can be used for monitoring temperature, strain, water level, humidity, etc. Grating devices in polymer optical fiber (POF) have attracted interest in recent years due to their potential applications in various fields, especially biomedical. Chapter 3 presents the state of the art about fabrication technology of grating devices in different kinds of POFs and explores potential sensing application scenarios, and it focuses on the fabrication of chirped POF-FBG devices and the potential application of such devices.

Chapter 4 shares the development of several optical fiber platforms for an ammonia gas–sensing application based on modifying an optical fiber cladding layer through an etching and tapering process. This modification extends the evanescent wave to propagate outside of the optical fiber and thus enhances its interaction with the analyte. Chapter 5 studies the integration of FBG sensors into a single-channel and a multichannel spectrum-sliced wavelength division multiplexed passive optical network (SS-WDM-PON). The operation of both sensor and data transmission systems, over a shared optical distribution network (ODN), is also evaluated to

The use of stimulated Raman scattering (SRS) as a means of amplifying signals in telecommunication systems has not been widely used because of the lack of reliable high-power pump sources. Raman fiber laser (RFL) could be used for this
