摘要

使用优化的腰高斯-拉盖尔型态表示进行了腔稳定性的详细研究。通过G-L模式下往返矩阵的展开和随后的对角化，得到了模态特性在腔几何上的参数缩放，包括增益重叠、散射和翼削损耗，以及衍射。侧向开洞的模态腰围由相对于/spl的往返系数的优化得到。利用PREVEU数值算法对数学模型方程进行快速数值求解，得到了往返模态损失的数值。

Tailoring of transverse and longitudinal mode stability in extended cavity VCSELs, using paraxial eigenmode algorithms

A detailed study of cavity stability is conducted using an optimized waist Gauss-Laguerre representation of cavity modes. The parametric scaling of modal properties on cavity geometry including gain overlap, scattering and wing-clipping losses, in addition to diffraction, is obtained via an expansion of the round-trip matrix in G-L modes and subsequent diagonalization. Modal waist in laterally open cavities follows from the optimization for the round trip coefficient relative to /spl omega//sub 0/. Numerical values for the round trip modal losses are obtained through a fast numerical solution of the mathematical model equations, using the numerical algorithm PREVEU.
