Abstract :
We use the finite difference time domain method (FDTD) to investigate polarisation control of single-photon emission from single quantum dots confined in elliptical micro-pillar microcavities. In contrast to circular pillars, one of the cavity modes has smaller modal volume and maintains high Q-factor.
