Handbook Of Distributed Feedback Laser Diodes Second Edition

Since the first edition of this book was published in 1997, the photonics landscape has evolved considerably and so has the role of distributed feedback (DFB) laser diodes. Although tunable laser diodes continue to be introduced in advanced optical communication systems, DFB laser diodes are still widely applied in many deployed systems. This also includes wavelength tunable DFB laser diodes and DFB laser diode arrays, usually integrated with intensity or phase modulators and semiconductor optical amplifiers. This valuable resource gives professionals a comprehensive description of the different effects that determine the behavior of a DFB laser diode. Special attention is given to two new chapters on wavelength tunable DFB laser diodes and bistable and unstable DFB laser diodes. Among many other updates throughout the reference, semi-conductor and electromagnetic professionals are also provided two new appendices. This book fully covers the underlying theory, commercial applications, necessary design criteria, and future direction of this technology.

Concentrating on presenting a thorough analysis of DFB lasers from a level suitable for research students, this book emphasises and gives extensive coverage of computer aided modeling techniques.

The accumulative demand for high-bandwidth communications has been liable for the hasty development of Optical Communication Systems (OCS). These systems employ fiber optics to convey electromagnetic waves, and need to take into account the undesired effects of dispersion and reduction on the bandwidth. In recent year, distributed feedback laser was one of the substantial topics that have been study for many years. It was introduced and developed by Kogelnik and Shank. Since that model release, people are now recognizing distributed feedback laser are imperative to human requisite. Distributed feedback lasers are useful item in society or the world because it provides the phase difference between the gain and the index grating based on using power series method to resolve the couple-wave equation that reveals the calculation of the threshold gain margin which located in complex-couple distributed feedback laser.This handbook brings together cutting-edge research and reviews on distributed feedback laser diodes; illustrates the method of calculation the threshold gain margin that play important role in the optic world. This volume is intended to the study of semiconductor lasers with distributed feedback (DFB), namely their usage as the light source in high bit rate optical communication systems (OCS). This is particularly important in situations where direct modulation (DM) of the emitter is used. In addition, it also presents emphasis how distributed feedback laser (DFB) play important role in optic world and the advantage or disadvantage of using DFB. The fabrication of high-efficiency distributed feedback laser diodes is described.

This unique practical handbook is the only one of its kind to provide the conceptual framework and troubleshooting tactics related to the manufacturing, selection, and installation of modern photonic networks, including optical fiber plants, optical transceivers, test and measurement equipment, and network architecture of SDH, OTN, IP/MPLS, FTTx networks, and PON. This resource includes the latest technological advancements and industry applications while covering the entire fiber ecosystem from installation to troubleshooting. This book presents the use of common tools like LPM (laser source and power meter) to overcome common issues related to optical patching and fiber plants and also discusses the use of specialized tools including the optical time domain reflectometer (OTDR) for issues with fiber plants and locating fiber breaks.
