This book provides a unified and complete theory for semiconductor lasers, covering topics ranging from the principles of classical and quantum mechanics to highly advanced levels for readers who need to analyze the complicated operating characteristics generated in the real application of semiconductor lasers.

The author conducts a theoretical analysis especially on the instabilities involved in the operation of semiconductor lasers. A density matrix into the theory for semiconductor lasers is introduced and the formulation of an improved rate equation to help understand the mode competition phenomena which cause the optical external feedback noise is thoroughly described from the basic quantum mechanics. The derivation of the improved rate equation will allow readers to extend the analysis for the different types of semiconductor materials and laser structures they deal with.

This book is intended not only for students and academic researchers but also for engineers who develop lasers for the market, as the advanced topics covered are dedicated to real problems in implementing semiconductor lasers for practical use.

Explains how to handle the basic equations and how to design semiconductor lasers to achieve more efficient and higher performance Introduces unified analyses based on the classical and quantum mechanics for interaction between the optical wave and the electrons Formulates an improved rate equation to treat dynamics of the lasing operation on the basis of the density matrix Provides a theoretical explanation of the instability of the lasing mode and generation of the optical external noise and introduces suppressing schemes for these inferior properties Includes supplementary material: sn.pub/extras
