摘要
本文导出了任意折射分布的多量子阱波导芯子区域的转移矩阵,用非等效折射近似得到了TE和TM两种偏振的色散关系.理论的精确性经数值计算比较证明是完全可靠的.
Dispersion relations for TE and TM modes of a multiple quantum well (MQW) waveguide with an arbitrary refractive index profile are derived in the approximation of non-equivalent refractive index with the help of the trandfer matrix technique. The accuracy of the theory is examined by comparison with an exact analysis for a step-index MQW waveguide.
