Abstract
Method of manufacturing an optical device, and an optical device, the optical device having one or more layers () of quantum-dots located in-between barrier layers (). A spacer layer () is grown on a barrier layer (), such that the spacer layer () is adapted for substantially blocking strain fields induced by quantum-dot layers, thereby producing a smooth growth front for a subsequent barrier layer ().
