Abstract
We present the magneto-optical investigation of coupling between single exciton spin state of an InGaAs QD and a high quality micropillar cavity. Due to Purcell effect, we realize the selective enhancement of spin polarized photon emission from a single quantum dot-micropillar cavity system by tuning external magnetic field.
