DIRECTIONAL ENTANGLEMENT IN COUPLED QUANTUM-DOT PHOTONIC BAND-GAP MICROCAVITY SYSTEMS

M.‐A. Dupertuis, Raphael Färber

Summary: We investigate pairs of isolated quantum dot excitons strongly coupled to microcavity, and quantum dot biexciton, as sources of directionnal entanglement in photonic bandgap microcavity circuits. Characteristics are compared, also with polarisation entanglement in microcavity.

MULTISTABILITY IN A CHIRAL SEMICONDUCTOR MICROCAVITY

O. A. Dmitrieva, Николай Алексеевич Гиппиус, S. G. Tikhodeev

The features of the bi- and multistability effects in the semiconductor Bragg microcavity with chiral photonic crystal slab on the upper mirror are investigated theoretically. It is shown that the response of such a chiral structure under a linearly polarized coherent resonant pump demonstrates sharp multistable transitions with abrupt jumps of the exciton intensity and degree of circular polarization. It is shown that of the thresholds of bistable transitions in the system with different sense of circular polarization differ slightly, i.e. in case of a non-optimized structure, we can expect to obtain even a larger amplitude of the jumps of the degree of circular polarization of the excitonic response due to the multistability than in a specially optimized chiral structure with a high degree of circular polarization at low pump intensity.The features of the bi- and multistability effects in the semiconductor Bragg microcavity with chiral photonic crystal slab on the upper mirror are investigated theoretically.

CHAOTIC DYNAMICS OF HIGH DENSITY PHOTON AND EXCITON SYSTEM

NGUYEN TRUNG DAN, Nguyen Ba An, Le Ngoc Minh

We consider nonlinear dynamics of a system of interacting photons and excitons driven by a resonantly exciting light field. Using the linear stability analysis for nonlinear coupled equations of photon and exciton operators we investigated that, besides the usual unstable domain which is a negative slope branch, there are other unstable ones in the leftmost and rightmost sides of the lower and upper branches of the frequency-density bistable curves. Numerical study shows that the system has very rich information on the instability nature and a self-oscillation process leading to chaos can occur in these unstable domains.We consider nonlinear dynamics of a system of interacting photons and excitons driven by a resonantly exciting light field.
