Abstract

InGaAsP/GaAs SCH SQW lasers have been prepared by LP-MOCVD. The dependence of threshold current density (J_th) on cavity length (L) was explained by threshold current condition and gain characteristics diodes samples with output power of 1 to 2 W, threshold current density (J_th) of 330 to 450 A/cm² and external differential quantum efficiency ((eta) _d) 35% to 75%, are in good agreement with the designed requirement.
