Quantum dot nano structures are interesting for applications in information technology and play a growing role in data storage, medical and biological applications. Understanding quantum nanomaterials is thus the key for the conception and optimization of novel structures.This monograph gives an overview of the theory and introduces the concepts of advanced computational modelling of quantum dot nanomaterials and devices ranging from phenomenological models up to fully quantum theoretical description.

Modern advanced semiconductor lasers show complex spatio-temporal dynamics of the emitted optical fields. This book presents fundamental theories and simulations of the spatio-temporal dynamics and quantum fluctuations in semiconductor lasers. The dynamic interplay of light and matter is theoretically described by taking into account microscopic carrier dynamics, spatially dependent light-field propagation and the influence of spontaneous emission and noise. Microscopic simulations reveal the internal spatio-temporal dynamics of in-plane lasers, high-power amplifiers and vertical-cavity surface-emitting lasers. The theory developed here provides the basis for the interpretation of measured emission properties and may serve as a predictive guideline for the design of advanced semiconductor lasers.
