Single-mode Optical Fibres

This book describes signal propagation in single-mode optical fibres for telecommunication applications. Such description is based on the analysis of field propagation, considering waveguide properties and also some of the particular characteristics of the material fibre. The book covers such recent advances as, coherent transmissions; optical amplification; MIR fibres; polarization maintaining; polarization diversity and photon counting.

For graduate and post-graduate students, researchers and technicians, interested both in electromagnetic field theory and in optical communications.
