The first guided-wave components that employed signals in the form
of light beams traveling along thin films were fabricated a little
more than two decades ago. The parallel development of
semiconductor lasers and the subsequent availability of low-loss
optical fibers made possible the imple mentation of completely
optical systems for communications, signal pro cessing and other
applications that had used only electronic circuitry in the past.
Referred to as integrated optics, this technology has been rein
forced by utilizing electronic components that act as controlling
elements or perform other functions for which the optical
counterparts are not as effec tive. The broader area thus generated
was aptly named optoelectronics and it currently represents a
fascinating, rapidly evolving and most promising technology.
Specifically, the amalgamation of electronic and optics compo nents
into an integrated optoelectronics format is expected to provide a
wide range of systems having miniaturized, high speed, broad band
and reliable components for telecommunications, data processing,
optical computing and other applications in the near and far
future. This book is intended to cover primarily the optical
portion of the op toelectronics area by focusing on the theory and
applications of components that use guided optical waves. Hence all
aspects of integrated optics are dis cussed, but optoelectronic
components having primarily electronic rather than optical
functions have not been included. Each chapter has been writ ten by
experts who have actively participated in developing the specific
areas addressed by them."
This research monograph presents a systematic treatment of the
theory of the propagation of transient electromagnetic fields (such
as optical pulses) through dielectric media which exhibit both
dispersion and absorption. The work divides naturally into two
parts. Part I presents a summary of the fundamental theory of the
radiation and propagation of rather general electromagnetic waves
in causal, linear media which are homogeneous and isotropic but
which otherwise have rather general dispersive and absorbing
properties. In Part II, we specialize on the propagation of a
plane, transient electromagnetic field in a homogeneous dielectric.
Although we have made some contributions to the fundamental theory
given in Part I, most of the results of our own research appear in
Part II. The purpose of the theory presented in Part II is to
predict and to explain in explicit detail the dynamics of the field
after it has propagated far enough through the medium to be in the
mature-dispersion regime. It is the subject of a classic theory,
based on the research conducted by A. Sommerfeld and L.
Because integrated optics and optoelectronics technology have been
devel oping very rapidly during the past few years, significant
advances have been made since the first edition of this book was
published. Furthermore, interest in the book itself has been
strong, leading to a demand for a new, updated version of the text.
This has motivated us to issue the present revised pa perback
edition, whose lower price will make it more easily accessible to
researchers in the area and to interested graduate students, in
particular. The present edition is essentially similar to the
original hardcover book, except that a new chapter (Chap. 7) has
been added, which briefly reviews the recent advances in the area
and provides new references. Typographical errors spotted in the
original edition have also been corrected. Although great care has
been exercised, some errors may still occur in the text and other
improvements could be introduced in a possible future edition. The
volume editor would therefore appreciate any comments from readers,
who are urged to communicate their suggestions directly to him."
