Abstract :
1.3 μm-range GaInNAsSb quantum well lasers that include small amount of Sb as the composition were confirmed to increase the critical thickness at which the growth mode changes from the 2-dimentional (2-D) growth to the 3-dimentional (3-D) growth. By adopting GaNAs barriers instead of GaAs barriers, we obtained the very low Jth of 160A/cm2/well up to 5QWs. We applied this material to the VCSELs, and the obtained threshold currents of 10ch-arrays are as uniform as 1.85±0.15mA at 25°C.
