Distributed Feedback Laser Diodes and Optical Tunable Filters (eBook)

Advances in optical fibre based communications systems have played
a crucial role in the development of the information highway. By
offering a single mode oscillation and narrow spectral output,
distributed feedback (DFB) semiconductor laser diodes offer
excellent optical light sources as well as optical filters for
fibre based communications and dense wavelength division
multiplexing (DWDM) systems. This comprehensive text focuses on the
basic working principles of DFB laser diodes and optical filters
and details the development of a new technique for enhanced system
performance.

* Considers the optical waveguiding characteristics and
properties of semiconductor materials and the physics of DFB
semiconductor lasers.

* Presents a powerful modelling technique based on the transfer
matrix method which can be used to improve the design of laser
diodes, optical fibres and amplifiers.

* Examines the effect of the various corrugation shapes on the
coupling coefficients and lasing characteristics of DFB laser
diodes.

* Technical advice to improve immunity against the spatial hole
burning effect.

* Extensive referencing throughout and a comprehensive glossary
of symbols and abbreviations.

* Suitable for both introductory and advanced levels

This is an indispensable textbook for undergraduate and
postgraduate students of electrical and electronic engineering and
physics as it consolidates their knowledge in this rapidly growing
field. As a technical guide for the structural design of DFB laser
diodes and optical filters, the book will serve as an invaluable
reference for researchers in opto-electronics, and semi conductor
device physics.
