Abstract :
The fabrication and characterisation of buried ridge DFB lasers integrated with butt coupled, strip loaded passive waveguides prepared by selective area MOVPE is described. Lasing threshold currents were as low as 10 mA and waveguide output powers in excess of 3 mW were achieved for 1 mm long waveguide devices.
