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.

However, this cavity is much smaller, being approximately 250-500 nm long, 5 15
(im wide, and 0. 1-0.2 /xxm thick. These dimensions are commonly referred to as
the longitudinal, lateral, and transverse dimensions of the cavity, respectively.
In a Fabry-Perot cavity, the photon lifetime is1 rp-K"+i,n^)=> (4-49) For a typical
value of gu, = 50 cm-1 and a refractive index in the lasing material of n = 3.5, the
photon lifetime is approximately rph = 2ps. This value sets the upper limit to the ...
In general, edge-emitting LEDs have gaussian near-field output profiles with \/el
full widths of approximately 0.9 and 22 /xm in the directions perpendicular and
parallel to the junction plane, respectively. The far-field patterns vary
