Distributed Feedback Laser Diodes: Principles and Physical Modelling

Distributed Feedback Laser Diodes Principles and Physical Modelling H. Ghafouri-Shiraz B. S. K. Lo University of Birmingham, UK 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 an excellent optical light source for fibre-based communication systems. This comprehensive text focuses on the basic working principles of DFB laser diodes 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 filters 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.
