Abstract :
A simple approach to the butt coupling between a 1.5 mu m BRS type DFB laser and a passive waveguide, based on the vapour phase growth properties on a nonplanar substrate, is reported. Stable single longitudinal mode emission is achieved for devices with CW threshold currents as low as 17 mA. An output power of 2 mW is measured from a 1.1 mm long passive waveguide.
