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.

4.3.8 Temperature Effects An important factor to consider in the application of
laser diodes is the temperature dependence of the threshold current kh(T). This
parameter increases with temperature in all types of semiconductor lasers
Here, Ea is an activation energy characterizing the lifetime rs, kB is Boltzmann's
constant, T is the absolute temperature at which rs was evaluated, and K is a
constant. The problem in establishing such an expression is that several
6.6 TEMPERATURE EFFECT ON AVALANCHE GAIN The gain mechanism of an
avalanche photodiode is very temperature-sensitive because of the temperature
dependence of the electron and hole ionization rates.44"46 This temperature ...
