摘要：
We propose a new semianalytical method using variational analysis for developing an equivalent three-layer model of a multiple-quantum-well waveguide. Waveguiding properties such as effective index and field distribution of this equivalent waveguide are compared with those of previously reported equivalents and with the results obtained from the exact multilayer analysis of the multiple-quantum-well waveguide. The waveguiding properties are accurately predicted by this method, and the computational effort is significantly reduced. (C) 1995 Optical Society of America
