This book introduces the physical principles of optical fibers, and details their use in sensor technology and modern optical communication systems. The authors begin by setting out the basic propagation characteristics of single mode

We then show how the recently developed matrix method can be used to calculate accurately the bending loss in such waveguides. We then suggest a novel refractive-index profile for which the bending losses can be made extremely small.
