【摘要】 采用数值分析来模拟半导体激光器的功率输出特性被认为是便捷、有效的方法。本文以量子阱激光器为研究对象,首先从其内部的有源层电子跃迁速率方程出发,采用低复杂度的微分法确定内量子效率、阈值电流密度及漏电流等参量与工作温度间的函数关系,建立了精确的数值分析模型。进而,将模拟结果与实验测试结果及Optiwave软件的模拟结果进行比较。数值结果表明,所建立的分析模型有效克服了Optiwave软件的不足,实现了全注入电流域内的模拟输出,增强了模拟结果与实验结果间的近似度与精确度,平均误差仅为3.88%。更多还原

【Abstract】 It is an expedient and efficient method to simulate the output power characteristic of a laser diode through the numerical analysis.In this paper,firstly,based on the rate equation of the electrons transition in the active layer,the functions of some key parameters,such as internal quantum efficiency,threshold current and leakage current,etc.,are defined with the variance of working temperature.And an accurate numerical analytical model is built by adopting the low-complicity difference method.Then,the simulated results are compared with the results from testing and Optiwave software.The results show that,by using the proposed analytical model,the simulation on the output power characteristic of a laser diode can be realized in the all fields of the input current,which overcomes the drawbacks within the Optiwave software.At the same time,the deviation between the simulated results and testing results is reduced obviously,and the average error is only 3.88%.更多还原
