Wavelength design for the 941nm high output power strained single-quantum-well semiconductor lasers

从薛定谔方程出发推导了阶梯形有限深应变单量子阱中的特征值方程 ,研究了台阶宽度对激射波长、电子第一子能级、空穴第一子能级的影响以及空穴第一子能级对激射波长的影响 ,计算结果表明当有源区In组分较大时 ,不能忽略空穴第一子能级对激射波长的影响 .该模型计算结果与实验值相吻合 .

The eigenvalue equation of the step finite strained single quantum well is deduced from Schrdinger equation, the influence of the step width on first electron energy, first hole energy, the stimulated wavelength, and the influence of the first hole energy on stimulated wavelength are studied. The results indicate that, if the In content is large, the influence of the first hole energy on the stimulated wavelength should not be neglected. The calculated value by using this model is in accord with the experiment results.
