Fiber-optic communication systems have revolutionized our telecommunication infrastructures currently, almost all telephone land-line, cellular, and internet communications must travel via some form of optical fibers. In these transmission systems, neither the phase nor frequency of the optical signal carries information only the intensity of the signal is used. To transmit more information in a single optical carrier, the phase of the optical carrier must be explored.

As a result, there is renewed interest in phase-modulated optical communications, mainly in direct-detection DPSK...

This book details parametric down-conversion for the generation of non-classical state of light and its applications in generating various kinds of quantum entanglement among multiple photons from parametric down-conversion. It presents applications of the principle of quantum interference to multi-photon systems. The book also details continuous variable entanglement and various types of multi-photon interference effects.

In addition to expanding and clarifying a number of sections of the first edition, it generalizes the analysis that eliminates the noncausal pre-acceleration so that it applies to removing any pre-deceleration as well. It also introduces a robust power series solution to the equation of motion that produces an extremely accurate solution to problems such as the motion of electrons in uniform magnetic fields.

Basic Electromagnetism and Materials is the product of many years of teaching basic and applied electromagnetism. This textbook can be used to teach electromagnetism to a wide range of undergraduate science majors in physics, electrical engineering, or materials science. However, by making lesser demands on mathematical knowledge than competing texts, and by emphasizing electromagnetic properties of materials and their applications, this textbook is particularly appropriate for students of materials science. Many competing texts focus on the study of propagation waves either in...

Choice Outstanding Title (January 2006)

Since the discovery of the lasers in 1960 and optical fibers in 1970, optics underwent deep changes which accentuated its multi-field character. This work covers essential concepts of comprehension and reports the great progress of current knowledge in optics. The method of presentation is inspired by Richard Feynman, with an emphasis on "telling" optics, rather than deducing it from fundamental laws. For its excellent teaching style, the book received the Arnulf-Francon Award by the French Optical Society. The concepts are formulated in a...

A pulse of light spreads in time as it propagates in a fiber due to the physical phenomenon called dispersion. While dispersion can be deleterious in optical communications systems, it can also be exploited to manage the temporal and spectral shapes of pulses and their interactions with other pulses. Much of dispersion control is realized in optical communications systems with discrete devices - the so-called dispersion compensators, and almost all commercially deployed dispersion compensators today are based on specially designed fibers. This book addresses various aspects of this device...
