摘要
利用低压金属有机化学气相沉积(LP-MOCVD)生长了无铝980 nm InGaAs/InGaAsP/InGaP单量子阱(SQW)激光器, 测试了含铝的InGaAs/GaAs/AlGaAs和无铝的InGaAs/InGaAsP/InGaP两种不同材料的980 nm InGaAs SQW激光器在30~70 ℃范围内的P-I-V特性曲线, 对比分析了两种材料系980 nm激光器输出光功率、阈值电流、斜率效率和激射波长随温度的变化, 并对InGaAs/InGaAsP/InGaP激光器进行了可靠性实验。
Abstract
An aluminum-free InGaAs/InGaAsP/InGaP single quantum well (SQW) laser diode (LD) is grown by low-pressure MOCVD. The P-I-V characteristics of Al-free and Al-containing 980-nm InGaAs lasers are tested in temperature range of 30-70 ℃. The variations with temperature of the two different LDs’ characteristic parameters, including output power, threshold current, slope efficiency, and the wavelength, are analyzed contrastively. The reliability experiments on the InGaAs/InGaAsP/InGaP laser diodes are also carried out.
