Paper Abstract

Recently there ar some reports on the AlInGaAs/AlGaAs material system with emission wavelength in the range of 800-890nm. The AlInGaAs/AlGaAs strained quantum well lasers are usually grown by metal-organic chemical vapor deposition and there are few of them that have been grown by solid- source molecular beam epitaxy (MBE). In this paper we report the characteristics of AlInGaAs/AlGaAs strained quantum well materials and lasers grown by MBE. A typical 10K photoluminescence spectrum with FWHM value of 10 meV is comparable with that of GaAs/AlGaAs quantum well materials. InAlGaAs/AlGaAs strained quantum well lasers with a emission wavelength of 810nm were fabricated, the threshold current density is 375 A/cm2 for broad-area lasers, and it decreases to 290 A/cm2 when the cavity length extend to 1600 micrometers an external differential quantum efficiency of 0.92 W/A and narrow perpendicular beam divergence of 32 degrees are demonstrated for the uncoated lasers with cavity length of 800 micrometers .
