量子级联激光器波导模型中有效Refractive Index和限制因子的修正

Correction to the Effective Refractive Index and the Confinement Factor in Waveguide Modeling for Quantum Cascade Lasers

Ming Lyu, Claire Gmachl

摘要:

本文导出了量子级联激光器波导设计中的有效介质折射率和限制因子的计算公式,与以往文献中的计算公式相比,应用严格的微扰理论,考虑了波导结构和材料的各向异性光学增益和非厄米特性的影响,对限制因子和有效增益作了百分之几的修正。这个结果可以很容易地推广到任何具有分层结构的光学器件。

英文摘要:

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.
