多量子阱波导等效折射率的新公式

New formula of equivalent refractive index in MQW waveguides

利用转移矩阵技术,建立了薄膜近似下的多量子阱波导芯子区域等效折射率的解析公式。该公式是偏振态和量子阱波导折射率分布的函数。

A new formnal of equivalent refractive index in the core-section of the multl quantum wells (MQW) waveguide is developed for the two polarizations in the thin film approximation. It can be applied to an arbitary refractive index profile of the MQW waveguide.
