Paper Abstract

We present photoluminescence and modal gain measurements in a Ga(NAsP) single-quantum well sample pseudomorphically grown on silicon substrate. The temperature dependence indicates that disorder induced localization effects dominate the low temperature photoluminescence spectra. Nevertheless, using the variable stripe length method, we observe modal gain values up to 15 cm-1 at room temperature. These values are very promising, demonstrate the high optical quality of the new dilute nitride material Ga(NAsP) and underline its candidacy for electrically pumped lasers on silicon substrate.
