The possibility to tune the emission wavelength and to reduce the linewidth of self-organized dots is studied. Thin layers of In0.5Ga0.5As was selectively deposited on nanoscale InP islands on (100)GaAs. A tuning range of 100 meV was achieved for the emission from the dots. Also, a minimum FWHM of 8.5 meV was measured from an ensemble of dots, showing that the heteroepitaxial layer on the islands tends to homogenize the active volume of the dots.
