In hybrid systems which consist of semiconductor nanostructures and dielectric photonic crystals significant aspects of the light-matter interaction can be tailored. Such structures are described by a microscopic theory which provides a self-consistent solution of the dynamics of the electromagnetic field and the material excitations. The theory is applied to investigate spatial inhomogeneneities of the optical properties, in particular, excitonic resonances, wave packet dynamics, and the optical gain are analyzed [1,2]. Additionally, the optical properties of quantum wells embedded in one-dimensional photonic crystals are investigated. If such structures are placed inside a microcavity, the gain increases superlinearly with the number of wells [3].
