Abstract :
An index-guiding structure capable of providing well-controlled single-mode operation has been realized for Ga
xIn
1-xAS
yP
1-y/InP lasers (

, and

m) using a terraced substrate (TS) configuration prepared by single-step LPE growth. The threshold current was reduced to as low as 44 mA and single-transverse and longitudinal mode operation was stably achieved up to 2.8 times the threshold. Continuous operation at room temperature was also demonstrated.
