Abstract :
The optical confinement factor, far-field angle, and threshold current of 1.3 μm AlGaInAs/InP separate confinement heterostructure (SCH) laser with two-stack AlInAs-(AlGa)InAs multiquantum barriers (MQB) are theoretically studied. The internal quantum efficiency for the laser with MQB is decreased by 13% in contrast to 24% for the laser without MQB in the temperature range of 298-348 K. The characteristic temperature can be improved by 10 K. Experimental results for the 1.3 μm AlGaInAs/InP laser with MQB are also presented and compared
