Abstract :
Strongly index-coupled GaInAsP/InP membrane DFB laser, consisting of a flat single-quantum-well active region, was realized by adopting a surface corrugation structure. A threshold pump power as low as 1.1 mW was achieved under RT-CW condition for the stripe width of 2.0 mum and the cavity length of 60 mum. The index-coupling coefficient was estimated to be 3,200 cm-1 for the surface corrugation depth of 50 nm
