This chapter discusses mathematical modeling as a key component in the design of devices and systems in optoelectronics projects. One thrust of the book has been to lay out the physical and mathematical modelling techniques for the electromagnetic and electronic interactions within distributed feedback lasers to give better explanations and to facilitate new designs. Optical systems where arrays of devices may be interconnected are one such important area and are discussed. Novel concepts such as that of the push-pull laser, tunable lasers with Bragg gratings, and surface-emitting lasers are all candidate areas for applications of the modelling principles given in this text. The future for mathematical modelling, coupled with a sound physical under standing, is bright, extensive and assured.
