Description: Since the publication of the first edition of this book in 1989, the field of
nonlinear fiber optics has virtually exploded. A major factor behind such a
tremendous growth was the advent of fiber amplifiers, made by doping silica
or fluoride fibers with rare-earth ions such as erbium and neodymium. Such
amplifiers revolutionized the design of fiber-optic communication systems, including
those making use of optical solitons whose very existence stems from
the presence of nonlinear effects in optical fibers. Optical amplifiers permit
propagation of lightwave signals over thousands of kilometers as they can compensate
for all losses encountered by the signal in the optical domain. At the
same time, fiber amplifiers enable the use of massive wavelength-division multiplexing
(WDM) and have led to the development of lightwave systems with
capacities exceeding 1 Tb/s. Platform: |
