This book, written specifically for use by advanced undergraduate and first year graduate students, provides a detailed problematic approach to the study of the fundamental mathematical and physical principles of the latest applications in the field of optics. It begins with the study of geometric optics, covering paraxial ray optics, third-order aberration and characteristic functions. The formulas for aberrations are derived from first principles using Luneberg's treatment starting from Hamilton's equations. The rest of the book is devoted to the modern physical optics. The subjects covered include diffraction, coherance, Fourier optics and holography, as well as the salient aspects of sell-focussing of light beams, graded index optical waveguides and evanescent waves and the Goos-hanchen effect.

This textbook provides senior undergraduates studying modern optics with a comprehensive account of optics and optical electronics. A large number of solved and unsolved problems are included in the book. The extensive coverage makes it valuable to postgraduates, and also to optical engineers, as a source of basic design information. The initial chapters cover the basic principles involved in the propagation of electromagnetic waves. These are followed by a description of diffraction and its application to spatial frequency filtering and holography. Laser theory and the various types of laser are covered, as well as the theory of optical waveguides, fibre optics and integrated optics. The final chapters cover electrooptics, acoustooptics, and nonlinear optical effects.

Recent advances in the development of low-loss optical fibers have revolutionized the field of telecommunications, and fiber-based networks form a key part of international communications systems. This book introduces the physical principles of optical fibers, and details their use in sensor technology and modern optical communication systems. The authors begin by setting out the basic propagation characteristics of single mode and multimode optical fibers. In later chapters they cover optical sources, optical detectors, and fiber-optic communication system design. They also treat a wide variety of related topics such as doped fiber amplifiers, dispersion compensation, fiber sensors, and measurement techniques for the characterization of optical fibers. Throughout the book, physical and engineering aspects of the subject are interwoven, and many worked examples and exercises are included. It will be an ideal textbook for undergraduate or graduate students taking courses in optical fiber communications, photonics, or optoelectronics.

Ever since their invention in 1960, lasers have assumed tremendous importance in the fields of science, engineering and technology because of their use both in basic research and in various technological applications. Lasers: Theory and Applications 2nd Edition will provide a coherent presentation of the basic physics behind the working of the laser along with some of their most important applications. Numerical examples are scattered throughout the book for helping the student gain a better appreciation of the concepts and problems at the end of each chapter and provides the student a better understanding of the basics and help in applying the concepts to practical situations. This book serves as a text in a course on lasers and their applications for students majoring in various disciplines such as Physics, Chemistry and Electrical Engineering.

An introductory, easy-to-understand and purely non-mathematical text
Covers state-of-the-art developments in the field of fiber optics - fiber amplifiers, dispersion compensation and non-linear effects. Discusses basics of lasers with emphasis on special properties and applications. Adopts an application-oriented approach-applications explained with interesting illustrations. Provides examples and comparisons from day-to-day experience, wherever feasible, to make readers understand by correlation of known facts. The book is designed to serve as a popular reference on fiber optics and lasers. It will not only interest general readers and students, but will also serve as a useful reference to working professionals in the field of lasers and fiber-optic communication system.

Fiber Optic Essentials starts with a basic discussion on lightwaves and the phenomenon of refraction and reflection. It then goes on to introduces the reader to the field of fiber optics and covers some of the recent developments, such as fiber amplifiers, dispersion compensation and nonlinear effects. A number of other applications are also presented. Examples and comparison with everyday experience are provided wherever possible to help the reader's comprehension. Diagrams are also included to aid in the visualization of certain concepts.

In this book we begin with Fermat's principle and obtain the Lagrangian and Hamiltonian pictures of ray propagation through various media. Given the current interest and activity in optical fibers and optical communication, analysis of light propagation in inhomogeneous media is dealt with in great detail. The past decade has witnessed great advances in adaptive optics and compensation for optical aberrations. The formalism described herein can be used to calculate aberrations ofoptical systems. Toward the end of the book, we present application of the formalism to current research problems. Of particular interest is the use of dynamic programming techniques which can be used to handle variational/extremum problems. This method has only recently been applied to opticalproblems.

This book covers fundamental principles and wide array of numerical based problems, patterned as perFAQs in university exams. Answers follow the problems section by detailed conceptual explanationsand student friendly step-wise solution.

A collection of problems in electromagnetics for the undergraduate level, this book covers the basics as well as some applied aspects. Many of these problems have evolved over the past decade of teaching the course to undergraduate students. The problems are at various levels of difficulty starting from the simplest. Solutions to all problems have also been provided.
