| 摘 要： | 计算了InGaAsPSBH激光器的TE00模,并利用非傍轴矢量矩理论,分析了平行于p-n结方向上的光学质量因子My2在以往有关M2的计算中,往往忽略了包层中光场的贡献,因此得出M2小于1的结论当半导体激光器的激活层的尺寸远小于发射波长时,大部分光场将渗透到包层中,因此,包层的光场是不能忽略的考虑到激活层和包层中的光场对M2的影响,给出了非傍轴半导体激光M2的精确表达式结果表明,My大于1.

| Abstract: | The horizontal beam quality factor M2y of the TE00 propagating mode for InGaAsP (λ＝1.3 μm) SBH lasers has been investigated. It has been shown that the optical fields penetrate deeply into the waveguide and cladding layers when the width of the active layer is smaller than emission wavelength. The field distributions outside the active layer will influence the beam quality factor. The calculated non-paraxial M2y is larger than unity. |
