High density, uniform InAs quantum dots (QDs) have been grown on InxGa1-xAs/InP matrix by metal-organic vapor phase epitaxy (MOVPE) using a two-step growth method. By sandwiching the InAs QDs between InxGa1-xAs barrier layers, emission wavelength of the InAs/InxGa1-xAs/InP QD structures reaches >2.3 mum.
