- Coherent_effects_in_semiconductor_optics abstract "The interaction of matter with light, i.e., electromagnetic fields, is able to generate a coherent superposition of excited quantum states in the material.Coherent denotes the fact that the material excitations have a well defined phase relation which originates from the phase of the incident electromagnetic wave.Macroscopically, the superposition state of the material results in an optical polarization, i.e., a rapidly oscillating dipole density.The optical polarization is a genuine non-equilibrium quantity that decays to zero when the excited system relaxes to its equilibrium state after the electromagnetic pulse is switched off.Due to this decay which is called dephasing, coherent effects are observable only for a certain temporal duration after pulsed photoexcitation. Various materials such as atoms, molecules, metals, insulators, semiconductors are studied using coherent optical spectroscopy and such experiments and their theoretical analysis has revealed a wealth of insights on the involved matter states and their dynamical evolution.This article focusses on coherent optical effects in semiconductors and semiconductor nanostructures.After an introduction into the basic principles, the semiconductor Bloch equations (abbreviated as SBEs) which are able to theoretically describe coherent semiconductor optics on the basis of a fully microscopic many-body quantum theory are introduced.Then, a few prominent examples for coherent effects in semiconductor optics are described all of which can be understood theoretically on the basis of the SBEs.".
