Описание: Laser beam combining techniques allow increasing the power of lasers far beyond what it is possible to obtain from a single conventional laser. One step further, coherent beam combining (CBC) also helps to maintain the very unique properties of the laser emission with respect to its spectral and spatial properties.

Presents the technological advancements that enable high spectral-efficiency and high-capacity fiber-optic communication systems and networks
This book examines key technology advances in high spectral-efficiency fiber-optic communication systems and networks, enabled by the use of coherent detection and digital signal processing (DSP). The first of this book's 16 chapters is a detailed introduction. Chapter 2 reviews the modulation formats, while Chapter 3 focuses on detection and error correction technologies for coherent optical communication systems. Chapters 4 and 5 are devoted to Nyquist-WDM and orthogonal frequency-division multiplexing (OFDM). In chapter 6, polarization and nonlinear impairments in coherent optical communication systems are discussed. The fiber nonlinear effects in a non-dispersion-managed system are covered in chapter 7. Chapter 8 describes linear impairment equalization and Chapter 9 discusses various nonlinear mitigation techniques. Signal synchronization is covered in Chapters 10 and 11. Chapter 12 describes the main constraints put on the DSP algorithms by the hardware structure. Chapter 13 addresses the fundamental concepts and recent progress of photonic integration. Optical performance monitoring and elastic optical network technology are the subjects of Chapters 14 and 15. Finally, Chapter 16 discusses spatial-division multiplexing and MIMO processing technology, a potential solution to solve the capacity limit of single-mode fibers.
- Contains basic theories and up-to-date technology advancements in each chapter

Описание: The phenomenon of photorefraction was discovered in 1966 in studies of propagation of a fairly powerful laser beam through the electro-optic crys- tals LiNb0, LiTa0, and some other compounds. The laser beam illumi- 3 3 nating part of the sample was found to cause a local change in the refrac- tive index of the crystal, thereby leading to distortion of the beam's wave front. The light had deteriorated the initially high optical quality of the crystal, in other words, it had given rise to a nonuniform distribution of the refractive index in the illuminated region. The effect was first called "opti- cal damage". The practical significance of the phenomenon was soon appreciated, applications were proposed, and a . vast amount of activity began. In the years that followed, the phenomenon was termed the "photorefractive ef- fect". Because of the reversible behavior of the refractive index variations due to photorefraction, photorefractive crystals have been regarded as re- cyclable photosensitive media. This became a valuable finding for optical engineers engaged in holography and optical information processing. On the other hand, the research into the nature of the photorefractive effect proved to be of considerable interest to physicists working in the fields of solid-state physics, semiconductors, and coherent optics.
