论文摘要
量子级联激光器的波导设计中有效的培养基折射率的方程是通过应用严格的摄动理论以及包括各向异性光学增益的效果，并应限制了材料的限制，将其用于先前文献中所使用的方程，并包括各向异性光学上的增益和非透明度的限制。该结果很容易被推广到具有分层结构的任何光学设备。
The equations for the effective medium refractive index and for the confinement factor in the waveguide design for quantum cascade lasers are derived.Compared to equations used in prior literature, by applying rigorous perturbation theory and including the effect of the anisotropic optical gain and non-Hermitian properties of the waveguide structure and materials, a few percent correction should be made to the confinement factor and the effective gain. This result can easily be generalized to any optical devices with a layered structure.
