A microscopic, fully quantum mechanical analysis for the spontaneous emission of selectively excited semiconductor microcavities is outlined. The theory is numerically evaluated to compute the spectral properties and the pulsed emission dynamics of the system.1 Introduction In the last decades, semiconductors and their optical properties have been the subject of intense research. Whereas most of these studies are done in the semi-classical regime, the improving quality of man-made semiconductor heterostructures makes it more possible to study also quantumoptical effects. In the theoretical analysis of semi-classical light-matter interaction effects in semicondcutors, only the electronic system is described fully quantum-mechanically while the electro-magnetic pulses are assumed to be classical. Only few attempts have been made to take both the many-body effects of the interacting carrier Fermi system and the quantum nature of light seriously, see e.g. [1,2].Besides high-quality quantum wells (QW) and quantum dots, also semiconductor microcavity systems are promising for the investigation of quantum-optical effects. The coupling between the resonance mode of the cavity and the excitonic QW resonance leads to a double peaked normal-mode spectrum [3] which dominates the optical response for low to moderate excitation densities. While most aspects of the semiclassical regime are well understood [4], quantum-optical features are emerging only gradually. In former publications, we have already presented and analyzed cases where quantum-optical features have led to surprising results in traditional pump-probe experiments [5,6]. These investigations were crucial first steps in developing semiconductor systems towards quantumoptical applications. In the present paper, we show how a fully microscopic theory of semiconductor electrons interacting with a quantized light field explains experiments where a strong enhancement of the incoherent light emission at the energy of a single one of the normal mode resonances can be obtained by selectively exciting this peak. This emission occurs in the form of relatively short incoherent pulses.

“…The coherent part of the equations constitutes the well-known semiconductor Bloch equations [5], while the incoherent part leads to the semiconductor luminescence [4,6]. The coupling between coherent and incoherent dynamics, made possible by the quantized light field, leads to interesting quantum-optical effects in seemingly classical experiments [7,8] and to coherent control of incoherently emitted light [9]. Moreover, the theory has interesting implications for the interpretation of luminescence signals in connection with exciton formation [10,11].…”

“…The correct three-dimensional treatment of the cavity mode leads to a structured continuum of guided modes that can have an influence on the luminescence, 56 and plays an important role in the observation of a quantum-fluctuation-induced third peak in the pump-probe spectrum of microcavities. 57 In Fig. 12͑a͒ RRS signals are shown that have been computed for a microcavity consisting of a spacer embedded in ten and 12.5 pairs of distributed Bragg reflectors.…”

Resonance Rayleigh scattering from semiconductor heterostructures: The role of radiative coupling

The resonance Rayleigh scattering from disordered semiconductor heterostructures is investigated. Within a generalized transfer-matrix approach, the propagation of the optical field and the linear material response in the presence of disorder are solved self-consistently. To investigate the role of radiative coupling, studies for a single quantum well, multiple quantum wells, and a quantum well embedded in a microcavity are performed. It is shown that the dynamics of the resonance Rayleigh scattered signals is not only determined by the underlying disorder potential, but also by the properties of the polaritonic eigenmodes of the system. In certain cases the polaritonic coupling effects even dominate over the disorder.
