Book Description
Stimulated Brillouin scattering (SBS) is the most important example of a stimulated scattering process-light scattering that occurs when the intensity of the light field itself affects the propagating medium. A phenomenon that has been known of for some 35 years in solid state laser research, it has recently become relevant in the optical fiber ind

Book Description
Scattering is the collision of two objects that results in a change of trajectory and energy. For example, in particle physics, such as electrons, photons, or neutrons are "scattered off" of a target specimen, resulting in a different energy and direction. In the field of electromagnetism, scattering is the random diffusion of electromagnetic radiation from air masses is an aid in the long-range sending of radio signals over geographic obstacles such as mountains. This type of scattering, applied to the field of acoustics, is the spreading of sound in many directions due to irregularities in the transmission medium. Volume I of Scattering will be devoted to basic theoretical ideas, approximation methods, numerical techniques and mathematical modeling. Volume II will be concerned with basic experimental techniques, technological practices, and comparisons with relevant theoretical work including seismology, medical applications, meteorological phenomena and astronomy. This reference will be used by researchers and graduate students in physics, applied physics, biophysics, chemical physics, medical physics, acoustics, geosciences, optics, mathematics, and engineering. This is the first encyclopedic-range work on the topic of scattering theory in quantum mechanics, elastodynamics, acoustics, and electromagnetics. It serves as a comprehensive interdisciplinary presentation of scattering and inverse scattering theory and applications in a wide range of scientific fields, with an emphasis, and details, up-to-date developments. Scattering also places an emphasis on the problems that are still in active current research. The first interdisciplinary reference source on scattering to gather all world expertise in this technique Covers the major aspects of scattering in a common language, helping to widening the knowledge of researchers across disciplines The list of editors, associate editors and contributors reads like an international Who's Who in the interdisciplinary field of scattering

Book Description
This book, the first dedicated to the topic, provides a comprehensive treatment of forward stimulated Brillouin scattering (SBS) in standard optical fibers. SBS interactions between guided light and sound waves have drawn much attention for over fifty years, and optical fibers provide an excellent playground for the study of Brillouin scattering as they support guided modes of both wave types and provide long interaction lengths. This book is dedicated to forward SBS processes that are driven by co-propagating optical fields. The physics of forward SBS is explained in detail, starting from the fundamentals of interactions between guided optical and acoustic waves, with emphasis given to the acoustic modes that are stimulated in the processes. The realization of forward SBS in standard single-mode, polarization-maintaining and multi-core fibers is then discussed in depth. Innovative potential applications in sensors, monitoring of coating layers, lasers, and radio-frequency oscillators are presented. This book introduces the subject to graduate students in optics and applied physics, and it will be of interest to scientists working in fiber-optics, nonlinear optics and opto-mechanics. Provides the first treatment of forward stimulated Brillouin scattering (SBS) in book form; Reflects the dramatic recent increase in interest in forward SBS processes , driven in part by the promise of new fiber sensing concepts; Delivers a solid and comprehensive grounding in the physics of forward SBS along with detailed experimental set-ups, measurement protocols, and applications.

Book Description
The dynamical behavior of stimulated Brillouin scattering (SBS) under a variety of conditions is investigated both theoretically and experimentally. Under conditions of a single continuous-wave laser field, the initiation of the SBS process is treated by including the thermal fluctuations of the material density which lead to spontaneous Brillouin scattering. Predictions are made for the threshold of the Stokes light. The spectrum of the output Stokes light is predicted to exhibit gain-narrowing as the input laser intensity is increased. Under certain conditions, the Stokes output intensity is expected to exhibit nearly 100% fluctuations even far above the threshold for SBS. Experiments performed in a single-mode optical fiber verify many of the predictions of the theory. Stimulated Brillouin scattering in the presence of two counterpropagating laser beams is studied. Under these conditions, the laser beams become temporally unstable to the growth of Stokes and anti-Stokes light. For the case when the input intensities of the two waves are comparable, the threshold for instability can be significantly lower than he threshold for usual single-beam SBS and, for the case of a broad Brillouin line, the system can show a period-doubling route to chaos. This Brillouin instability was observed experimentally using carbon disulfide as the Brillouin-active material.

Book Description
This report results from a contract tasking Dr, Robert G Harrison as follows: The contractor will investigate expansion of his existing computer code in order to model Stimulated Brillouin Scattering (SBS) in an optical fiber and its dependence on numerical aperture and laser power He will investigate the appearance of both stochastic and deterministic elements in the observed SBS and using his modified computer model, determine the optimum conditions for generating steady-state SBS with maximum efficiency.

Book Description
Brillouin Scattering, Volume 109 in the Semiconductors and Semimetal series, marks the centenary of Leon Brillouin’s seminal 1922 paper which provided a detailed theory of the effect that now bears his name. Stimulated Brillouin Scattering (SBS) is the strongest third order optical nonlinearity and plays an important role in contemporary science and applications, particularly lasers, communications, and fibre optics, as well as playing a new role in experimental physics and the life sciences. This volume provides a foundational perspective on Brillouin scattering, starting with a historical review of Brillouin scattering, the theory of SBS and the convergence between SBS and Optomechanics. We then consider SBS in several different waveguide geometries, including photonic crystal fibres, integrated optics and superfluids. From the leading researchers in the field Historical, theoretical, and scientific perspective Pedagogical
