Polariton quantum blockade in a photonic dot 论文

摘要

We investigate the quantum nonlinear dynamics of a resonantly excited photonic quantum dot embedding a quantum well in the strong exciton-photon coupling regime. Within a master equation approach, we study the polariton blockade effect due to polariton-polariton interactions as a function of the photonic dot geometry, spectral linewidths and energy detuning between quantum well exciton and confined photon mode. The second order coherence function ${g}^{(2)}(t,{t}^{\ensuremath{'}})$ and the photon antibunching are calculated for both continuous wave and pulsed excitations.
