DOWNLOAD EBOOK →Stimulated 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.

DOWNLOAD EBOOK →Wavelength-division multiplexing (WDM) enables multiple communication links to use a common transmission fiber by transmitting a multitude of different wavelengths at the same time. This chapter describes WDM technology, including options such as coarse and dense WDM defined by standards such as ITU-T Recommendations G.652 to G.657. The wavelength spectrum allocation for the L-, C-, S-, E-, and O-bands is discussed. Related technologies, such as time-division multiplexing and erbium-doped fiber amplifiers, are also described in this context. Topics include service mapping using the generic framing procedure and virtual concatenation, technology for optical transceivers and filters, reconfigurable optical add/drop multiplexers, fiber Bragg gratings, and array waveguides. WDM link budgets and noise sources are also discussed, including rings and other topologies, protection schemes, dispersion compensating fiber, equalization, and modulation options including extensions to 100G.

DOWNLOAD EBOOK →Considering the key evolutions within the access network technologies as well as the unprecedented levels of bandwidth demands by end users, this book condenses the relentless research, design, and deployment experience of state-of-the-art access networks. Furthermore, it shares the critical steps and details of the developments and deployment of these emergent technologies; which is very crucial particularly as telecommunications vendors and carriers are looking for cost-effective ultra-broadband “last-mile” access solutions to stay competitive in the “post bubble” era. The book is written to provide a comprehensive overview of the major broadband access technologies and deployments involving internationally recognized authors and key players. Due to its scope and depth, the proposed book is able to fill an important gap of today’s available literature.
