We report the effects of accumulated strain by stacking on the surface and optical properties of stacked 1.3 mm InAs/GaAs quantum dot (QD) structures grown by MOCVD. It is found that the surface of the stacked QD structures becomes more and more undulated with stacking, due to the increased strain i
