    Sammanfattning : This thesis deals with the fabrication and characterization of integration compatible semiconductor lasers. An extensive investigation of electron-beam lithography (EBL) and chemically assisted ion beam etching (CAIBE) for the fabrication of vertical ultra- high quality facets in GaAs, as well as a systematic characterization of grating coupled surface emitting lasers is presented.
