Abstract

Semiconductor laser diodes are key components in optical fiber communication, data storage, sensing, material processing, and other applications. They are based on sophisticated interactions of electrons and photons in semiconductor nanostructures (see Chapter 3). Advanced theoretical models and simulation tools are required for the development and analysis of future generations of laser diodes. The following chapters describe some of these complex models in detail. This introductory chapter is aimed at readers who are not yet familiar with basic models and parameters of semiconductor lasers. By exploring simple analytical models, this chapter tries to develop an intuitive understanding of internal laser physics that will help to digest the more complicated theory outlined in subsequent chapters. While these analytical models are quite popular, they often have limits beyond which numerical simulations are required, as shown below.
