Abstract
We employ a quantum master equations approach based on a full-wave Maxwell-pseudospin model to describe the polarisation dynamics of a negatively charged quantum dot embedded in a micropillar cavity upon an ultrashort optical excitation. The set of equations is solved self-consistently in the time domain by the Finite-Difference Time-Domain method (FDTD). We demonstrate numerically a giant optical polarisation rotation ( ±π/2) of a resonant circularly polarised pulse in realistic dot-cavity geometries. The model allows for optimisation of the polarisation rotation angle for realisation of spin-photon entanglement and ultrafast polarisation switching on a chip.
