High Power InGaAsP/GaAs SCH SQW Lasers
摘要
Abstract
InGaAsP/GaAs SCH SQW lasers have been prepared by LP-MOCVD. The dependence of threshold current density on cavity length was explained. Laser diodes are characterized by the output power of 1 W to 2 W, threshold current density (Jth) of 330 A/cm2to 450 A/cm2and external differential quantum efficiency (ηd) of 35% to 75%, and these characteristics are in good agreement with the designed requirement.
