Theory of polariton-mediated Raman scattering in microcavities.

چکیده
We calculate the intensity of the polariton-mediated inelastic light scattering in semiconductor microcavities. We treat the exciton-photon coupling nonperturbatively and incorporate lifetime effects in both excitons and photons, and a coupling of the photons to the electron-hole continuum. Taking the matrix elements as fitting parameters, the results are in excellent agreement with measured Raman intensities due to optical phonons that are resonant with the upper polariton branches in II-VI microcavities with embedded CdTe quantum wells.

Polariton Lasing Due to the Exciton–Electron Scattering in Semiconductor Microcavities
The issue of polariton lasing in n-doped microcavities is addressed. We show theoretically that the introduction of a cold electron gas into quantum microcavities induces efficient electron–polariton scattering. This process allows the condensation of the polaritons accumulated at the bottleneck to the final emitting state with a transition time of a few picoseconds, opening the way to a new ge...
متن کاملHyper Raman Scattering in Microcavity Quantum Wells: A Quantum Optical Process in the Strong Coupling Regime
We analyze the hyper Raman scattering process in a quantum well grown inside a semiconductor microcavity and present a microscopic calculation of emission spectra as a function of excitation energy, detuning, and angles. The exciton±photon coupling is treated non-perturbatively to include polariton effects and the Coulomb interaction between electrons is treated beyond the mean field approximat...
متن کاملQuantum theory of spin dynamics of exciton-polaritons in microcavities.
We present the quantum theory of momentum and spin relaxation of exciton-polaritons in microcavities. We show that giant longitudinal-transverse splitting of the polaritons mixes their spin states, which results in beats between right- and left-circularly polarized photoluminescence of microcavities, as was recently experimentally observed [Phys. Rev. Lett. 89, 077402 (2002)]]. This effect is s...

© Springer-Verlag Berlin Heidelberg 2015 Y.S. Zhao (ed.), Organic Nanophotonics, Nano-Optics and Nanophotonics, DOI 10.1007/978-3-662-45082-6_2 Abstract The photophysics of planar microcavities which employ organic materials as the optically resonant medium to achieve the strong-coupling regime is discussed. While as a result of the light–matter coupling, cavity polariton branches appear which ...
متن کاملStimulated secondary emission from semiconductor microcavities.
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 bosoni...
