Updated and revised, this second edition provides a coherent presentation of the basic physics behind lasers, along with some of their most important applications. Numerical examples are scattered throughout the book, and problems are included at the end of each chapter.

This comprehensive book provides an introduction to the physical principles of optical fibres, and discusses in detail their use in sensor technology and modern optical communication systems. It will be an ideal textbook for undergraduate or graduate students taking courses in optical fiber communications, photonics, or optoelectronics.

A collection of problems in electromagnetics for the undergraduate level, this book covers the basics and some applied aspects. It includes problems in fundamental areas such as electrostatics, magnetostatics, wave propagation, reflection and refraction, and also in more complex areas such as magnetic circuits, metallic waveguides and dielectric waveguides.

Since the fabrication of the first laser in 1960, research and development in the area of optics has grown with tremendous speed. Optics has now become an extremely important area of study in schools, colleges and universities. The UN General Assembly has proclaimed 2015 as the International Year of Light and Light-Based Technologies. This book is a part of the celebration of the International Year of Light.

The Special Theory of Relativity is considered as one of the two major revolutions of the twentieth century. This title offers a brief biography of Einstein, before explaining (in an easy-to-understand manner) the basic physics and consequences of the Special Theory of Relativity.

Albert Einstein is still an icon for most people even though many other great scientists of the twentieth century have had more direct impact on our lives. Einstein's enduring public image has to do with the style of his science and social world around him. This book gives a glimpse of his science, philosophy, and his troubled personal life.

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.
