Observation of dressed‐exciton oscillating emission over a wide wavelength range in a semiconductor microcavity
TLDR
In this paper, the authors observed the dressed-exciton oscillating emission in the time domain and associated spectral splitting in the frequency domain from a GaAs single quantum well microcavity over a very broad range of cavity resonant wavelengths.Abstract:
We have observed the dressed‐exciton oscillating emission in the time domain and the associated spectral splitting in the frequency domain from a GaAs single quantum well microcavity over a very broad range of cavity resonant wavelengths. The spectral splitting and temporal oscillation period have been measured to be nearly constant over two orders of magnitude variation of pump intensity, which confirms the linear bosonic feature of Wannier excitons in the weak excitation regime.read more

Strong coupling phenomena in quantum microcavity structures
TL;DR: The physics of strong coupling phenomena in semiconductor quantum microcavities is reviewed in this paper, with most important developments having occurred in the last 5 years, and the results of reflectivity experiments at both normal and oblique angles of incidence, the effects of external electric and magnetic fields, and results of coherent Raman scattering experiments, including the observation of motional narrowing over the exciton disorder potential.

Femtosecond dynamics of semiconductor-microcavity polaritons in the nonlinear regime
TL;DR: In this paper, the femtosecond dynamics of cavity-polaritons in a semiconductor quantum microcavity were investigated, and it was shown that in the nonlinear regime with a strong resonant pump, normal mode splitting (vacuum Rabi splitting) was reduced due to saturation of the excitonic transition.

Chapter 1 - Theoretical Bases of the Optical Properties of Semiconductor Quantum Nano-Structures
Abstract: This chapter provides a theoretical background of the optical properties of semiconductor quantum nanostructures and emphasizes on how those properties vary from quantum wells to quantum dots and how they are influenced by the exciton effect. Semiconductor quantum wells in which a thin semiconductor film is sandwiched between different materials via heterojunctions confine electron motion in the two-dimensional thin-film plane. This two-dimensionality gives rise to new optical properties that are not observed in bulk materials: (1) such as optical absorption and gain spectra peculiar to the step like density of states, (2) strong exciton resonance clearly observable even at room temperature, and (3) large optical nonlinearity and an electric field-induced energy shift of the resonance, called the “quantum-confined Stark effect.” Multidimensional quantum-confinement structures, such as quantum wires and quantum dots, are expected to improve quantum-effect optical devices.

Spectroscopy of strongly coupled atom-cavity systems: A topical review
TL;DR: In this paper, a new nonperturbative regime of radiation-matter interaction is examined by considering atoms interacting with fields in exceptionally high quality cavities, and a general framework for the study of such systems is presented.

Collapses and revivals of exciton emission in a semiconductor microcavity: Detuning and phase-space filling effects
TL;DR: In this paper, the authors investigated the effect of higher-order exciton-photon interaction on the appearance of collapse and revival of light intensity of a quantum well embedded in a semiconductor microcavity.
