Abstract :
The integration technique utilizing the energy blue shift due to the lateral quantum confinement effect is presented. A low threshold current operation with stable single-mode property has been successfully obtained for a distributed-reflector (DR) laser by adopting wide and narrow wirelike active regions for the active and passive sections, respectively.
