A unified microscopic theoretical framework for the calculation of optical excitations in
molecular and semiconductor materials is presented. The hierarchy of many-body density …

The optical response of radiatively coupled semiconductor multiple-quantum-well structures
is investigated theoretically. It is shown that the transverse optical field leads to a coupling of …

Non-stationary spatio-temporal effects in semiconductor heterostructures are investigated for
optical excitation by solving the coupled Semiconductor Maxwell-Bloch equations where …

Interaction-induced processes are studied using the third-order nonlinear polarization
created in polarization-dependent four-wave-mixing experiments (FWM) on a ZnSe single …

We investigate the interaction and dephasing of the excitons in wide Z n S e/Z n 0.94 Mg
0.06 Se quantum wells by spectrally resolved, femtosecond four-wave mixing (FWM) …

A polariton-based theory of resonant Rayleigh scattering in quantum wells, ie, the linear
elastic scattering of light, near an excitonic resonance is developed to establish the …

It is shown how a phenomenological few-level description of coherent semiconductor optics
is related to microscopic density-matrix theory. It turns out that the few-level dynamics is not …

The propagation of excitonic polaritons is investigated in the nonlinear optical regime by real-
time-resolved pump-and-probe measurements on a femtosecond time scale. High-quality …

Publisher Summary This chapter focuses on the local fields in linear and nonlinear optics of
mesoscopic systems, and describes the local-field electrodynamics in mesoscopic media …

The homogeneous linewidths of excitons in wet-etched ZnSe quantum wires of lateral sizes
down to 23 nm are studied by transient four-wave mixing. The low-density dephasing time is …
