用于光纤通信的1.55μm DFB激光器的可靠性分析

Reliability Analysis of 1.55 μm DFB Laser Diodes for Optical Fiber Communication

对用于光纤通信的InP基1.55μmDFB激光器的可靠性进行了研究。测试并分析了100℃时100mA和150mA2种电流应力条件,经过1700h老化,测试分析了激光器特性随时间的变化情况,拟合出在100℃,150mA条件下的激光器寿命在1000h小时左右。根据实验结果对比,提出了一种新的利用温度、电流两个加速度变量同时进行加速老化,快速估计激光器寿命并分析其可靠性的方法。对新的寿命估算方法进行了详细的讨论。

Reliability of InP-based 1.55 μm distributed feedback laser diodes for optical fiber communication were researched. The aging tests of laser diodes at 100°C, 100 mA and 150 mA for 1700 h were performed respectively. The change in characteristics as a function of aging time for laser diodes was analysed. The laser diodes lifetime at the condition of 100°C and 150 mA is about 1000 h. An accelerating aging method using two accelerating variables for estimating laser diodes lifetime was presented based on the contrast of the experimental results.
