“…However, there are certain features that can only be described in terms of a quantum-mechanical treatment of the electromagnetic radiation. Among these are all kinds of phenomena that affect the photon statistics, like the generation of squeezed light by nonlinear optical techniques (Fox et al, 1995;Dabbicco et al, 1996) or the optical Stark effect with nonclassical light (Altevogt, Puff, and Zimmermann, 1997). The most important process, however, which requires a quantum description of light, is spontaneous emission.…”

The authors review the physics of ultrafast dynamics in semiconductors and their heterostructures, including both the observed experimental phenomena and the theoretical description of the processes. These are probed by ultrafast optical excitation, generating nonequilibrium states that can be monitored by time-resolved spectroscopy. Light pulses create coherent superpositions of states, and the dynamics of the associated phase relationships can be directly investigated by means of many-pulse experiments. The commonly used experimental techniques are briefly reviewed. A variety of different phenomena can be described within a common theoretical framework based on the density-matrix formalism. The important interactions of the carriers included in the theoretical description are the phonon interactions, the interactions with classical and quantum light fields, and the Coulomb interaction among the carriers themselves. These interactions give rise to a strong interplay between phase coherence and relaxation, which strongly affects the nonequilibrium dynamics. Based on the general theory, the authors review the physical phenomena in various semiconductor structures including superlattices, quantum wells, quantum wires, and bulk media. Particular results which have played a central role in understanding the microscopic origins of the relaxation processes are discussed in detail. CONTENTS

“…While photon number statistics are used quite regularly to characterize the emission from a system, most prominently for identifying single-photon sources [2], the buildup of coherence in lasers [3,4] or Bose-Einstein condensates [5,6], and in dynamic light scattering [7] or fluorescence correlation spectroscopy [8], they are currently not routinely used as a spectroscopic tool, although the important effect of the excitation photon statistics on the excited quasiparticles has been highlighted [9,10] and there have been theoretical predictions for excitation photon-statistics dependencies of several quantities, for example, excitation efficiencies of optically active excitons in nanostructures [11]. The most probable reason for neglecting this degree of freedom in experiments lies in the small amount of light sources which offer tunable photon statistics, although recently advances in this direction have been made experimentally [6,12,13] and theoretically [14][15][16]. It is widely known and well studied that almost every kind of optical amplification adds noise to the amplified signal [17].…”

We propose photon-statistics excitation spectroscopy as an adequate tool to describe the optical response of a nonlinear system. To this end we suggest to use optical excitation with varying photon statistics as another spectroscopic degree of freedom to gather information about the system in question. The responses of several simple model systems to excitation beams with different photon statistics are discussed. Possible spectroscopic applications in terms of identifying lasing operation are pointed out.

Photon statistics as a probe for exciton correlations in coupled nanostructures

Quantum light excitation of Coulomb-coupled nanostructures, such as semiconductor quantum dots or light harvesting molecules, is analyzed for fixed light intensity but different photon statistics. The theory predicts a different excitation efficiency of the exciting light ͑thermal, coherent, and squeezed light͒ on the creation of optically active excitons and biexcitons. In particular, measurable differences and a strong dependence for the creation efficiency of biexcitons on the photon statistics are obtained.
