In this paper, techniques of quantum dot interdiffusion such as impurity free vacancy disordering and ion implantation induced disordering as well as the selective area epitaxy by metal-organic chemical vapour deposition have been used to tune the emission wavelength of self-orgainsed quantum dot structures. Under optimized experimental conditions, large differential band gap energies have been achieved by all approaches which is essential for quantum dot-based photonic integrated circuits.
