Distributed Feedback Laser Diodes and Optical Tunable Filters

Distributed Feedback Laser Diodes and Optical Wavelength Tunable Filters deals with the advances in optical fibre based communication systems that 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 all-inclusive text focuses on the basic working principles of DFB laser diodes and optical filters and detail the development of a new technique for enhanced system performance.

This indispensable textbook is written in a highly informative manner. It combines extensive referencing with a comprehensive glossary of symbols and abbreviations.

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

This volume:

• 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.
• Offers technical advice to improve immunity against the spatial hole burning effect.
