Optical fiber communications
The third edition of this popular text and reference book presents the fundamental principles for understanding and applying optical fiber technology to sophisticated modern telecommunication systems.
Optical-fiber-based telecommunication networks have become a major information-transmission-system, with high capacity links encircling the globe in both terrestrial and undersea installations. Numerous passive and active optical devices within these links perform complex transmission and networking functions in the optical domain, such as signal amplification, restoration, routing, and switching. Along with the need to understand the functions of these devices comes the necessity to measure both component and network performance, and to model and stimulate the complex behavior of reliable high-capacity networks.

2.6 GRADED-INDEX FIBER STRUCTURE In the graded-index fiber design the
core refractive index decreases continuously with increasing radial distance r
from the center of the fiber, but is generally constant in the cladding. The most ...
3.5.1 Refractive-Index Profiles In the design of single-mode fibers, dispersion
behavior is a major distinguishing feature, since this is what limits long-distance
and very high-speed transmission. Comparing Figs. 3-3 and 3-16, we see that ...
The injection of electrons and holes into the device alters the refractive index of
the active layer directly below the stripe. The profile of these injected carriers
creates a weak, complex waveguide that confines the light laterally. This type of ...
