The first four chapters cover the basics of semiconductors, including band structures, optical transitions, optical waveguides, and optical resonators. The remaining chapters discuss operating principles and basic characteristics of semiconductor lasers, and advanced topics including dynamic single-mode lasers, quantum well lasers, and control of spontaneous emission. The reader need only be familiar with undergraduate-level electromagnetism and quantum mechanics. After reading this book, the student will be able to think critically about semiconductor lasers, and be able to read and understand journal papers in the field. This book will be essential to any advanced undergraduate or graduate student of semiconductor lasers, and any professional physicist or engineer looking for a good overview of the subject.
The book also bridges a wide gap between journal papers and textbooks, requiring only an undergraduate-level knowledge of electromagnetism and quantum mechanics, and helps readers to understand journal papers where definitions of some technical terms vary, depending on the paper. Two definitions of the photon density in the rate equations and two definitions of the phase-shift in the phase-shifted DFB-LD are explained, and differences in the calculated results are indicated, depending on the definitions.
Readers can understand the physics of semiconductor lasers and analytical tools for Fabry-Perot LDs, DFB-LDs, and VCSELs and will be stimulated to develop semiconductor lasers themselves.
