DOWNLOAD EBOOKStimulated Brillouin scattering is one of the dominant nonlinear effects in single mode optical fibers due to its low threshold. Its unique Lorentzian gain spectrum characteristic with the narrow linewidth of 20-30 MHz has enabled numerous of applications, such as optical signal processing, delay and light storage, optical spectrum analysis and distributed sensing. However, a fixed spectral characteristic cannot meet the requirements of a variety of applications. Therefore, an engineered, reconfigurable or arbitrary manipulated gain spectrum is of great importance. This book will start from the basics of stimulated Brillouin scattering and its principle for distributed fiber sensing and optical signal processing. The basic method for Brillouin gain spectrum engineering by the pump modulation and the superposition with Brillouin loss(es) will be introduced. As the main contain of this book, the application of Brillouin gain spectrum engineering in the field of static and dynamic distributed fiber sensing, and optical signal processing together with the advantages and benefits will be demonstrated in detail. Under the assistance of gain spectrum engineering, solutions have been proposed for drawbacks such as measurand resolution in static distributed fiber sensing, tradeoff between dynamic range and sensitivity in dynamic distributed fiber sensing, and inevitable Brillouin noise in optical and microwave photonic filters based on stimulated Brillouin scattering.

DOWNLOAD EBOOKStimulated Brillouin scattering is the most dominant nonlinear effect in single mode optical fibers. Its unique spectral characteristics, especially the narrow bandwidth of 20 – 30 MHz enable numerous applications, including optical spectrum analysis, delay and storage of light, distributed sensing and optical signal processing. Most of them would benefit from a reduction of the Brillouin gain bandwidth. This dissertation demonstrates several methods for significant reduction of the Brillouin gain bandwidth, including a multi-stage system, the superposition of the gain with two losses as well as the utilization of a frequency domain aperture. Thereby the Brillouin gain bandwidth can be reduced significantly down to 3 MHz, which equals 15% of the normal bandwidth. Furthermore, the reduced Brillouin gain bandwidth is employed for various applications. First, the resolution and the dynamic range of a Brillouin based optical spectrum analyzer are enhanced significantly. Second, a new technique for the storage of optical data packets, called Quasi-Light-Storage, is introduced and the maximum storage time is increased to 160 ns for 8 bit data packets. Finally, Brillouin scattering is used for the processing of optical frequency combs, leading to the generation high quality of mm- and THz-waves, as well as almost ideal sinc-shaped Nyquist pulse sequences.
