780nm InGaAsP/InGaP/AlGaAs High Power Semiconductor Laser

Abstract
Using metal organic chemical vapor deposition,we fabricate an InGaAsP/InGaP/AlGaAs single quantum well laser with a separate confinement heterostructure.We calculate the gain spectrum with and without the effect of interband relaxation.The peak wavelength of the PL spectrum is 764nm.Due to the In carry-over effect,the interface between InGaP and AlGaAs is not abrupt.The performance of the laser diodes into which a thin GaAsP interlayer is inserted is better than those with no such interlayer.The threshold current is decreased from 560 to 450mA,the slope efficiency is increased from 0.61 to 0.7W/A,and the output power is increased from 370 to 940mW.-
