本文提出了一种求解多通道激光二极管阵列腔模式的数值方法。该分析基于耦合模式理论，并包括每个反射面电场的适当边界条件。饱和增益也包括在内，饱和来自前向波和反射波。我们给出了不同于最近对两个具有不同增益和传播常数的信道的解析分析的结果。目前的工作预测“腔超模式”类似于“对称”和“反对称”波导超模式先前在文献中描述。这些腔模式的特点是在两个通道中强度相等，即使通道增益大不相同。
We present a numerical method for the solution of the cavity modes of a multichannel array of laser diodes. The analysis is based on coupled‐mode theory and includes the appropriate boundary conditions for the electric field at each reflecting facet. Saturable gain is also included, with saturation arising from both the forward‐going and reflected waves. We present results which differ from a recent analytic analysis for the case of two channels with different gains and propagation constants. The present work predicts ‘‘cavity supermodes’’ which are similar to the ‘‘symmetric’’ and ‘‘antisymmetric’’ waveguide supermodes previously described in the literature. These cavity modes are characterized by equal intensities in both channels even when the channel gains are grossly different.
