Book Description :

Odyssey of Light in Nonlinear Optical Fibers: Theory and Applications presents a collection of breakthrough research portraying the odyssey of light from optical solitons to optical rogue waves in nonlinear optical fibers. The book provides a simple yet holistic view on the theoretical and application-oriented aspects of light, with a special focus on the underlying nonlinear phenomena. Exploring the very frontiers of light-wave technology, the text covers the basics of nonlinear fiberoptics and the dynamics of electromagnetic pulse propagation in nonlinear waveguides. It also highlights some of the latest advances in nonlinear optical fiber technology, discussing hidden symmetry reductions and Ablowitz–Kaup–Newell–Segur (AKNS) hierarchies for nonautonomous solitons, state-of-the-art Brillouin scattering applications, backpropagation, and the concept of eigenvalue communication—a powerful nonlinear digital signal processing technique that paves the way to overcome the current limitations of traditional communications methods in nonlinear fiber channels. Key chapters study the feasibility of the eigenvalue demodulation scheme based on digital coherent technology by throwing light on the experimental study of the noise tolerance of the demodulated eigenvalues, investigate matter wave solitons and other localized excitations pertaining to Bose–Einstein condensates in atom optics, and examine quantum field theory analogue effects occurring in binary waveguide arrays, plasmonic arrays, etc., as well as their ensuing nonlinear wave propagation. Featuring a foreword by Dr. Akira Hasegawa, the father of soliton communication systems, Odyssey of Light in Nonlinear Optical Fibers: Theory and Applications serves as a curtain raiser to usher in the photonics era. The technological innovations at the core of the book form the basis for the next generation of ultra-high speed computers and telecommunication devices.

Book Description :

The field of nonlinear optics, which has undergone a very rapid development since the discovery of lasers in the early sixties, continues to be an active and rapidly developing - search area. The interest is mainly due to the potential applications of nonlinear optics: - rectly in telecommunications for high rate data transmission, image processing and recognition or indirectly from the possibility of obtaining large wavelength range tuneable lasers for applications in industry, medicine, biology, data storage and retrieval, etc. New phenomena and materials continue to appear regularly, renewing the field. This has proven to be especially true over the last five years. New materials such as organics have been developed with very large second- and third-order nonlinear optical responses. Imp- tant developments in the areas of photorefractivity, all optical phenomena, frequency conv- sion and electro-optics have been observed. In parallel, a number of new phenomena have been reported, some of them challenging the previously held concepts. For example, solitons based on second-order nonlinearities have been observed in photorefractive materials and frequency doubling crystals, destroying the perception that third order nonlinearities are - quired for their generation and propagation. New ways of creating and manipulating nonl- ear optical materials have been developed. An example is the creation of highly nonlinear (second-order active) polymers by static electric field, photo-assisted or all-optical poling. Nonlinear optics involves, by definition, the product of electromagnetic fields. As a con- quence, it leads to the beam control.

Book Description :

"Nonlinear optical effects are very well studied in optical fibers. However, most of these studies are restricted to fibers that support one spatial mode. Multimode fibers can provide several new nonlinear pathways due to intermodal effects, which makes light propagation through them difficult to understand. But several proposed applications have led to a resurgence in efforts to determine how nonlinearity manifests in multimode fibers. This thesis deals with many different studies undertaken to understand a subset of this large variety of nonlinear effects that occur inside a multimode fiber. The first part of the thesis looks at two different manifestations of intermodal nonlinearity, spatiotemporal solitons and nonlinear spectral effects. The existence and interaction of solitons in multimode fibers is considered. Solitons, or a solitary wave packet that maintains its shape during propagation, is a commonly observed nonlinear artifact that has several applications in fiber optics. Intermodal interaction is added to the picture and the stability and formation of solitary wave packets in a multimode fiber are studied using numerical simulations. Simulations and theory are also used to understand how solitons propagating in different modes of a multimode fiber interact with each other owing to nonlinearity. Nonlinear optics has been successfully exploited to generate sources with novel spectral profiles, including a broad supercontinuum, frequency-combs etc. A combination of several nonlinear effects in the medium is usually responsible for tailoring the source spectrum. Numerical results are presented that show a novel spectral suppression phenomenon in multimode fibers. Nonlinear spectral broadening is demonstrated through experimental results, using a special photonic crystal fiber. The second part of this thesis explores the impact of random linear coupling between modes in a multimode or multicore fiber and how it affects nonlinear coupling. Random linear coupling can occur due to several imperfections in a real optical fiber and is important to consider when modeling systems that employ multimode fibers, like in the case of space division multiplexing communication systems. A comprehensive theoretical model is proposed that can be used to simulate the average nonlinear behavior with any amount of random linear coupling present in the system. Specific regimes of linear coupling are found to be more detrimental to optical communication systems. An experimental study to quantify linear coupling in a multicore fiber, and future work pertaining to it, are also described."--Pages ix-x.

Book Description :

Nonlinear Fiber Optics deals with various nonlinear phenomena in optical fibers, including wave propagation, group-velocity dispersion, self-phase modulation, optical pulse compression, cross-phase modulation, stimulated Raman scattering and Brillouin scattering, and parametric processes. The implications of various nonlinear effects on the performance of light-wave systems are emphasized throughout. This book consists of 10 chapters and begins with an overview of the fiber characteristics that are important for understanding nonlinear effects in optical fibers. A brief historical perspective of the progress in the field of fiber optics is provided. Fiber properties such as optical loss, chromatic dispersion, and birefringence are discussed. Particular attention is paid to chromatic dispersion because of its importance in the study of nonlinear effects probed by using ultrashort optical pulses. The chapters that follow focus on wave propagation in optical fibers, along with group-velocity dispersion and self-phase modulation. A chapter is devoted to pulse propagation in the region of anomalous group-velocity dispersion, with emphasis on solitons. The book concludes with a discussion of parametric processes such as harmonic generation, four-wave mixing, and parametric amplification. This book is intended for researchers already engaged in or wishing to enter the field of nonlinear fiber optics, for scientists and engineers interested in optical fiber communications, and for graduate students enrolled in courses dealing with nonlinear optics, fiber optics, or optical communications.

Book Description :

Micro-ring resonators (MRRs) are employed to generate signals used for optical communication applications, where they can be integrated in a single system. These structures are ideal candidates for very large-scale integrated (VLSI) photonic circuits, since they provide a wide range of optical signal processing functions while being ultra-compact. Soliton pulses have sufficient stability for preservation of their shape and velocity. Technological progress in fields such as tunable narrow band laser systems, multiple transmission, and MRR systems constitute a base for the development of new transmission techniques. Controlling the speed of a light signal has many potential applications in fiber optic communication and quantum computing. The slow light effect has many important applications and is a key technology for all optical networks such as optical signal processing. Generation of slow light in MRRs is based on the nonlinear optical fibers. Slow light can be generated within the micro-ring devices, which will be able to be used with the mobile telephone. Therefore, the message can be kept encrypted via quantum cryptography. Thus perfect security in a mobile telephone network is plausible. This research study involves both numerical experiments and theoretical work based on MRRs for secured communication.

Book Description :

The title explain new technique of secured and high capacity optical communication signals generation by using the micro and nano ring resonators. The pulses are known as soliton pulses which are more secured due to having the properties of chaotic and dark soliton signals with ultra short bandwidth. They have high capacity due to the fact that ring resonators are able to generate pulses in the form of solitons in multiples and train form. These pulses generated by ring resonators are suitable in optical communication due to use the compact and integrated rings system, easy to control, flexibility, less loss, application in long distance communication and many other advantages. Using these pulses overcome the problems such as losses during the propagation, long distances, error detection, using many repeaters or amplifiers, undetectable received signals, pulse broadening, overlapping and so on. This book show how to generate soliton pulses using ring resonators in the micro and nano range which can be used in optical communication to improve the transmission technique and quality of received signals in networks such as WiFi and wireless communication.
