TLDR
In this article, the signal in a degenerate four-wave mixing experiment is calculated for excitonic dephasing due to quantum well roughness, and the signal is used to calculate the signal of a semiconductor.Abstract:
Inelastic scattering processes as well as static disorder lead to dephasing in semiconductors. The latter case is investigated here by calculating the signal in a degenerate four-wave mixing experiment. Special emphasis is given to excitonic dephasing due to quantum well roughnessread more

Microcavity Polaritons: Homogeneous and Inhomogeneous Broadening in the Strong Coupling Regime
TL;DR: In this paper, two main k-parallel to-scattering mechanisms, namely polariton-phonon scattering and the in-plane structural disorder of the quantum well, are considered.

Linear optical properties of semiconductor microcavities with embedded quantum wells
TL;DR: An overview of the theory of the linear optical response of planar semiconductor microcavities with embedded quantum wells is presented in this paper, where the optical properties close to the excitonic transition in the strong coupling regime are addressed and the formalism of exciton polaritons is used.

Spatial Optical Parametric Coupling of Picosecond Light Pulses and Transverse Relaxation Effect in Resonant Media
Tatsuo Yajima,Yoichi Taira +1 more
TL;DR: In this paper, the effect of transverse relaxation time T 2 on the third-order nonlinear optical process has been investigated, where two incident light pulses with wave vectors k 1 and k 2 generate a light wave with 2 k 2 - k 1 in resonant media, and the correlation trace (output light energy vs incident pulse separation) for this process provides a general means of obtaining information on ultrashort T 2 for both homogeneously and inhomogeneously broadened transitions, and for both t p (pulse width) T 2.

Nonequilibrium theory of the optical Stark effect and spectral hole burning in semiconductors.
TL;DR: In this paper, the influence of intense coherent laser fields on the electronic and optical properties of semiconductors has been investigated using nonequilibrium Green's function techniques and exploiting the analogies to superconducting and Bose-condensed systems.

Green's Functions for a Particle in a One-Dimensional Random Potential
TL;DR: In this article, the spectral density of a particle in a one-dimensional random potential, where the potential at each point is statistically independent of the potential in all other points, is calculated by solving the equation of motion for the probability distribution.

Line shape of time-resolved four-wave mixing
TL;DR: In this article, it was shown that the microscopic origin of the time dependence can be understood in terms of coherent exciton-exciton interactions, and that this behavior is more general and should be seen in numerous dense media where strong nonlinear interactions of polarizations occur.
