【摘要】 给出一个新的量子阱激光器等效电路模型，由量子阱激光器单模速率方程推导得到并在电路模拟程序ＳＰＩＣＥ中完成。该模型考虑了热辐射效应和分离限制区域（ＳＣＨ）内的载流子工作情况，给出了新的光增益表达式。并利用该模型对单量子阱激光器的小信号特性和瞬态大信号特性进行了预测，模拟结果表明和速率方程的直接求解结果吻合很好。更多还原

【Abstract】 A simple equivalent circuit model of quantum well laser (QW LD) which is derived by QW rate equations and is accomplished in the circuit simulation program SPICE. In the model, the thermionic emission effect and the carrier transport effects are considered and also the new gain expression is given. With the prediction for the small signal response and the transient large signal response of QW LD, the computer simulation results agree well with the direct numerical analysis of the rate equations.更多还原
