摘要
半导体激光器自诞生至今在技术和应用方面取得了飞跃的发展,作为精密度要求极高的光电子器件,其可靠性研究具有十分重要的现实意义。针对目前激光器可靠性研究存在的一些问题,首先,在对激光器的性能退化因素和规律进行深入分析后,综合考虑了半导体激光器在工作时性能退化存在可恢复的情况,建立了基于竞争失效理论的半导体激光器的可恢复退化模型;其次,考虑了冲击失效阈值的变化规律与冲击退化总量之间存在相关性,推导出了非确定阈值下的半导体激光器的可靠度变化规律。最后,利用实例数据对半导体激光器的可靠度退化规律进行评估,得到了确定阈值和非确定阈值下激光器可靠度的退化情况,并和现有的模型进行了对比,验证了本文模型的有效性和可行性。
Semiconductor laser has made great progress in technology and application since its birth.As an optoelectronic device with high precision,its reliability research has very important practical significance.In view of the present laser reliability research problems,first of all,after the analysis of the factors and laws of laser performance degradation,the recoverable degradation model of semiconductor laser based on competitive failure theory is established,this takes the performance degradation of semiconductor laser into consideration.Secondly,considering the correlation between the variation law of shock failure threshold and the total amount of shock degradation,the reliability variation law of semiconductor laser under the non-deterministic threshold is deduced.Finally,the reliability degradation law of the semiconductor laser is evaluated by using the example data,and the reliability degradation situation of the laser with defined threshold and non-defined threshold is obtained,and compared with the existing model,which verifies the effectiveness and feasibility of the model presented in this paper.
