Abstract

The optical and electrical properties of High Power AlGaAs/AlGaAs Infrared LED with DDH( Double power Double Hetero Junction) structure are investigated. The high power LED is recently studied in order to apply to high speed communication devices. The power out of AlGaAs/AlGaAs with DDH structure is 13.0[mW], the forward voltage is 1.45[V], and the average decrease rate of power out is about 5[%] after aging test. The optical and electrical properties of DDH structure LED are superior than that of SH structured LED. The DDH structured LED is suitable to the high speed communication devices.
