The field of nonlinear optics, which has undergone a very rapid
development since the discovery of lasers in the early sixties,
continues to be an active and rapidly developing - search area. The
interest is mainly due to the potential applications of nonlinear
optics: - rectly in telecommunications for high rate data
transmission, image processing and recognition or indirectly from
the possibility of obtaining large wavelength range tuneable lasers
for applications in industry, medicine, biology, data storage and
retrieval, etc. New phenomena and materials continue to appear
regularly, renewing the field. This has proven to be especially
true over the last five years. New materials such as organics have
been developed with very large second- and third-order nonlinear
optical responses. Imp- tant developments in the areas of
photorefractivity, all optical phenomena, frequency conv- sion and
electro-optics have been observed. In parallel, a number of new
phenomena have been reported, some of them challenging the
previously held concepts. For example, solitons based on
second-order nonlinearities have been observed in photorefractive
materials and frequency doubling crystals, destroying the
perception that third order nonlinearities are - quired for their
generation and propagation. New ways of creating and manipulating
nonl- ear optical materials have been developed. An example is the
creation of highly nonlinear (second-order active) polymers by
static electric field, photo-assisted or all-optical poling.
Nonlinear optics involves, by definition, the product of
electromagnetic fields. As a con- quence, it leads to the beam
control.
The object of this school, held at Cargese, Corsica (France) from
August 12th to 24th 1991, was the presentation of the field of
guided wave nonlinear optics in a comprehensive, coherent, and
heuristic fashion. It seems appropriate that this school began with
an historical introduction by Professor Nicolaas Bloembergen of
Harvard, the acknowledged "father" of nonlinear optics, in general,
and concluded with a round table discussion headed by Dr. Eric
Spitz, the Scientific Director of a multinational electronics
company interested in developing industrial applications of guided
wave nonlinear optics. The lectures covered both the theoretical
framework of the field and applications to basic scientific
research, optical communications and technical instrumentation.
Specific topics developed included materials for guided wave
nonlinear optics, nonlinear interactions using integrated optical
guides, nonlinear surface waves, solitons, fiber nonlinear optics,
ultra-fast coupler switching as well as the related topic of fiber
and integrated optical lasers and amplifiers. Lectures have also
been devoted to squeezed states, chaos and strange attractors. The
subjects covered by the school underlines one of the major ways in
which this field has evolved over the past thirty some odd years.
The path from the original experiments with materials requiring
mega-watt power lasers to the recent developments in guided wave
configurations using milliwatt power diode lasers is marked by the
conjunction of ever improving fundamental scientific comprehension
and continuing technological developments.

This book is devoted to the numerous phenomena arising from the
interplay between electromagnetic resonances and nonlinear optical
interactions. These resonances are associated with surface plasmas
or guided waves, excited in nonlinear optical resonators such as
prisms or grating couplers. Topics include rigorous theories of
diffraction by gratings in nonlinear optics, presented in a form
ready for numerical implementations; scattering the matrix
description in nonlinear optics leading to the phenomological
approach based on the use of poles and zeros and other behaviours.
