Introduction to Part Ium. In practice, waveguides used for optical communications are highly flexible fibers composed of nearly transparent dielectric materials. The cross-section of these fibers is small-comparable to a human hair-and generally is divisible into three layers as shown in Fig. I-1. The central region is t

Pulse spreadingal pulse propagates, it spreads out, due to the dispersive properties of the fiber. Clearly if this spread becomes sufficiently large the pulse will overlap with adjacent pulses, leading to a decrease in information-carrying capacity because of the loss of resolution at the end of the fiber.

Fiber illumination and pulse shapeby examining the shape of the pulse as it propagates, i.e. the distribution of energy within the pulse, or .. We derive the pulse shape at time . due to an impulse of initially zero width, from which we can describe the response of a pulse of arbitrary initial shape by convolution. The analysis incl

Nonuniform fibers length. In practice, however, this need not be the case because of imperfections in manufacturing techniques and external stresses acting on fibers. Even an ideal nonabsorbing fiber made from optically transparent materials has an innate variation along its length due to the molecular granularity o

Choreography

Material absorptionorm fiber. The materials which constitute the core and cladding of fibers used for communication purposes are, however, slightly absorbing. Thus, as a bound ray propagates, its power slowly attenuates due to absorption by the fiber, and, on a sufficiently long fiber, virtually all the initial power

Thrombolysis

Spatial transientys provide a complete description of light propagation on nonabsorbing fibers sufficiently far from the source, when virtually all leaky-ray power has been lost. We call this the .state. In this chapter our attention is turned to the region intermediate between the source and the onset of the spatia
