## Optical Fiber CommunicationsThe 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. |

For

**guided**modes , ß can assume only certain discrete values , which are

determined from the requirement that the mode field must satisfy Maxwell ' s

equations and the electric and magnetic field boundary conditions at the core -

cladding ...

5 Wave Equations for Step - Index Fibers * We now use the above results to find

the

**guided**modes in a step - index fiber . A standard mathematical procedure for

solving equations such as Eq . ( 2 - 36 ) is to use the separation - of - variables ...

This type of device is commonly referred to as a gain -

**guided**laser . Although

these lasers can emit optical powers exceeding 100 mW , they have strong

instabilities and can have highly astigmatic , two - peaked beams as shown in Fig
