The need for greater bandwidth has driven laser manufacturers towards the use of distributed feedback semiconductor (DFB) lasers with a well-defined single mode. These semiconductor diode-based devices are now essential components in a broad range of advanced optical systems. This text covers the materials, operation and design strategies of DFB lasers. It provides detailed accounts of large-signal time-domain numerical modelling techniques, which can be extended to optical systems and components other than DFB lasers. Numerical MATLAB programs are outlined in the text.Also available:Analogue IC Design: the current-mode approach - ISBN 0863412971Selected Topics in Advanced Solid State and Fibre Optic Sensors - ISBN 0852967799The Institution of Engineering and Technology is one of the world's leading professional societies for the engineering and technology community.
