چکیده
We find strong influence of final-state stimulation on the time-resolved light emission dynamics from semiconductor microcavities after pulsed excitation allowing angle-resonant polariton-polariton scattering on the lower-polariton branch. The polariton dynamics can be controlled by injection of final-state polaritons at densities below a polariton saturation density of 5x10(8) cm(-2). A bosonic enhancement factor in the dynamics of up to 700 is evaluated.

Polarisation rotation in resonant emission of semiconductor microcavities
We present the semi-classical theory of the non-linear propagation of polarized light in semiconductor microcavities. This formalism explains the mysterious rotation of the polarization plane of light emitted by a microcavity in the regime of stimulated scattering observed recently. The model describes the stimulated four-wave mixing in microcavities. We show that the exciton spin-splitting ind...
متن کاملPolarization control of the nonlinear emission of semiconductor microcavities.
The degree of circular polarization ( Weierstrass p ) of the nonlinear emission in semiconductor microcavities is controlled by changing the exciton-cavity detuning. The polariton relaxation towards K approximately 0 cavitylike states is governed by final-state stimulated scattering. The helicity of the emission is selected due to the lifting of the degeneracy of the +/-1 spin levels at K appro...
متن کاملInvestigation of possible microcavity effect on lasing threshold of nonradiative-scattering-dominated semiconductor lasers
The effect of enhanced rate of spontaneous emission on gain and lasing threshold of semiconductor microcavity lasers has not been discussed clearly. Some reports have suggested that the lasing threshold in microcavities could possibly be lowered due to the so-called Purcell effect. Here, we argue that gain in weakly coupled semiconductor cavities is a local phenomenon, which occurs due to stimu...
متن کاملModified spontaneous emission properties of CdS quantum dots embedded in novel three-dimensional microcavities
Modified spontaneous emission properties in the presence of confined photon modes inside the three-dimensional (3-D.) optical microcavities are demonstrated. Self-formed pyramidal-shaped semiconductor structures fabricated by selective-area growth technique are utilized as an optical microcavity in which discrete photon modes are generated. Noticeable modification of spontaneous emission from a...
متن کاملOptical parametric oscillaton in 1D semiconductor microcavities
We present an experimental investigation of parametric scattering processes and optical parametric oscillations in wire shaped, one-dimensional semiconductor microcavities. Far field emission patterns and corresponding band dispersion are studied by polarization resolved measurements and power dependence measurements under resonant and non-resonant excitation. The multiplicity of the photonic b...
