A quantitative text on nonlinear fiber optics, August 14, 2000
This review is from: Nonlinear Fiber Optics, Second Edition (Optics and Photonics) (Hardcover)
This is a serious book written at a graduate-student or advanced-under-graduate level for the practicing professional employed in designing optical telecommunications systems and components. I don't think the book was written with students particularly in mind, since (for example) there are no examples or problems in the book as typically found in university course work In his introduction, Agrawal says "[t]he book is aimed for researchers already engaged in or wishing to enter the filed of nonlinear fiber optics." As the title suggests, the book's emphasis is on nonlinear effects in optical fibers, as opposed to nonlinear effects in bulk materials.
The first chapter is pretty basic, and is mostly review material that describes things like the index cross section in an optical fiber, material issues, fabrication, chromatic dispersion, modal birefringence (which leads to polarization mode dispersion), non linear refraction and stimulated inelastic scattering. The review here is pretty brief (the chapter has only about 25 pages).
Chapter two develops the mathematics of wave propagation in optical fibers, including the mathematics of mode propagation and basic propagation equations derived from Maxwell's equations. This chapter actually develops several different differential equations; each based on various assumptions applicable to different pulse widths. These differential equations then form the basis for later investigations into various non-linear effects discussed in the book. Chapter two is thus a foundational chapter and should be read and understood completely before moving on. There is a brief discussion at the end of the chapter that describes numerical methods.
Chapter three describes group-velocity dispersion, including chromatic dispersion as well as dispersion-induced pulse broadening and higher-order dispersion and their implications for optical systems.
Chapter four introduces self-phase modulation and self steepening.
Chapter five describes optical solitons (including fundamental and higher order solitions), soliton lasers, and soliton-based communications systems.
Chapter 6 describes some techniques for optical pulse compression using gratings and chirped optical pulses. It also describes soliton-effect compressors.
Chapter 7 is devoted to the subject of cross-phase modulation, chapter 8 to stimulated Raman scattering, chapter 9 to stimulated Brillouin scattering, and chapter 10 to parametric processes, including four-wave mixing, parametric gain, and phase matching.
The book is quantitative, making (as you'd expect in a graduate text) liberal use of mathematics. The level of mathematics, however, should be well within the grasp of senior college students majoring in physics, engineering, or mathematics. The subject, however, is non-trivial, and you should expect this book to present a real intellectual challenge in reading and understanding all the details. I took about six months to finish the book, including time taken to fill in some details in the derivations and to plot some of the equations on my computer.
Agrawal makes good use of figures and illustrations, which I found particularly helpful. The book also has an adequate index that makes the book more valuable as a desk reference.
Each chapter cites a wealth of reference material in the literature so that any subject covered within its pages can be studied in more detail and from the original sources.
I would not make this a first study of nonlinear optics (although it was for me). Rather, I'd look for texts that discuss nonlinear effects qualitatively, and I'd try to expose myself to experiments that illustrate these nonlinear effects to gain a more qualitative understanding before diving into Agrawal's mathematical derivations. With a more qualitative basis first acquired, however, Agrawal's book is an invaluable tool for understanding the most obscure nonlinear effects in optical fibers.

The definitive sourcebook for nonlinear fibre phenomenon, April 5, 2000
This review is from: Nonlinear Fiber Optics, Second Edition (Optics and Photonics) (Hardcover)
This book is the first and foremost reference book on many aspects of nonlinear fibre effect. It is written for non-experts in fibres but is also an invaluable resource for those who are.
It starts off with a quick review of linear fibre characteristics (dispersion, loss, fabrication) and devotes a chapter each to a systematic study of how dispersion without nonlinearity and nonlinearity without dispersion affect pulse propagation. Higher order nonlinearity and dispersion are also covered.
From this introduction, the problem of having both nonlinearity and dispersion present is introduced, leading to solitons. This treatment does not go deeply into the algebraic solution of the NLS equation, but gives a good background of the properties of solitons.
Several other topics are covered which span a broad array of important nonlinear phenomenon in optical fibres under active research. This seems to be the book to buy if you need to know about solitons and other nonlinear effects, and is continually referenced.
