摘 要: | 观察了室温下工作的DH激光器退化现象,发现在短时间内退化的器件,除阈值升高外尚伴随着微分量子效率下降。对热稳定性良好,并对于较长时间(>250小时)阈值上升率(△J_(th)/J_(th)千小时)小于3%的器件,高温老化证明它们的寿命都能超过万小时量级。

On the degradation of AlGaAs/GaAs double-heterostructure lasers |
| |
Abstract: | The degradation phenomena of DH lasers operating at room-temperature have been observed. It is found that some lasers degrade in a short time and their differential quantum efficiencies decrease while the threshold currents increase. It has been demonstrated in aging test at elevated temperature that the life-time can exceed ten thousand hours if the thermal stability of a laser is good and the increase rate of its threshold current (△Jth/Jth 103 hours)within a longer peried(over 250 hours)is less than 3%. |
