Popis: Self-assembled InAs quantum dashes in the InP system were grown by gas source molecular beam epitaxy. Different growth parameters like buffer material, growth temperature and layer thickness were studied using scanning electron microscopy and photoluminescence measurements. Four layers of InAs dashes were embedded as active material in a SCH laser structure. Device data of broad area and ridge waveguide lasers are presented. Broad area lasers of 100 μm width showed a transparency threshold current density of 330 A/cm 2 and an internal efficiency of 62%.
