Product Description:
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 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. The book 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; and examines the effect of the various corrugation shapes on the coupling coefficients and lasing characteristics of DFB laser diodes. It also includes technical advice to improve the immunity against the spatial hole burning effect. This text should be suitable for senior students of electrical and electronic engineering and physics. As a technical guide for the structural design of DFB laser diodes, it should serve as a reference for researchers in optoelectronics, and semiconductor and device physics.
