Chip-scale integrated light sources have the potential to replace electronic components by photonic devices. In this thesis, we demonstrate GaAs-based semiconductor nanowires (NWs) monolithically grown on silicon ridge waveguides (WG) on a silicon-on-insulator platform and successful coupling of the lasing mode to the proximal WG. In addition, we prove tunability of the lasing mode by epitaxial gain control. For this, the material composition in radial quantum wells is varied and corresponding effects on the lasing performance are studied.
