Brillouin scattering is a fundamental nonlinear opto-acoustic interaction present in optical fibers with important implications in fields ranging from modern telecommunication networks to smart optical fiber sensors. This thesis is aimed at providing a comprehensive theoretical and experimental investigation of both forward and backward Brillouin scattering in next generation photonic crystal fibers in view of potential applications to above mentioned fields. We show in particular that these micro-structured optical fibers have the remarkable ability to either suppress or enhance photon-phonon interactions compared to what is commonly observed in conventional fibers. Firstly, this thesis provides a complete experimental characterization of several photonic crystal fibers using a novel highly-resolved distributed sensing technique based on Brillouin echoes. We perform distributed measurements that show both short-scale and long-scale longitudinal fluctuations of the periodic wavelength-scale air-hole microstructure along the fibers. Our mapping technique is very sensitive to structural irregularities and thus interesting for fiber manufacturers to characterize and improve the fiber uniformity during the drawing process. With this technique, we also report the first experimental observationof the acoustic decay time and the Brillouin linewidth broadening in both standard and photonic crystal fibers. Furthermore, we experimentally demonstrate a simplified architecture of our Brillouin echoes-based distributed optical fiber sensor with centimeter spatial resolution. It is based on differential phase-shift keying technique using a single Mach-Zehnder modulator to generate a pump pulse and a _-phase-shifted pulse with an easy and accurate adjustment of delay. These sensing techniques are also applied to distributed strain measurement. Another aspect of this thesis is the investigation of a novel method for suppressing stimulated Brillouin scattering that is detrimental to optical fiber transmissions and fiber lasers. We experimentally study several fibers and a demonstrate 4 dB increase of the Brillouin threshold in a photonic crystal fiber by varying periodically the core diameter by only7%. The efficiency of this passive technique is verified by use of our distributed sensing technique where the oscillating Brillouin frequency shift is clearly observed.Lastly, we present experimental and numerical results demonstrating the simultaneous vi Abstract frequency-selective excitation of several guided acoustic Brillouin modes in a photonic crystal fiber with a multi-scale structure design. These guided acoustic modes are identified by using a full vector finite-element model to result from elastic radial vibrations confined by the air-silica microstructure. We further show the strong impact of structural irregularities of the fiber on the frequency and modal shape of these acoustic resonances.

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

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.
