asymmetric coupling meaning in English
非对称接口
Examples
- The performance of modulators employing mqw is governed by the quantum confined stark effect . in order to simplify the analysis of mqw , we obtain an explicit formula concerning the correlations between the gaas / gaalas quantum well widths of finite potential barrier structure and those of infinite potential barrier structure under the condition that the ground state energies are equal at zero bias states . then the transfer matrix method is used to investigate the optical field distribution in the mqw waveguide based on five - step asymmetric coupled quantum well structure that is really used in the modulator
本论文首先根据量子限制stark效应，发展了等效宽度思想，提出了把单量子阱结构的有限深势阱的分析转化为无限深势阱模型的显式公式，从而大大简化了电场下量子阱结构的分析；接着利用转移矩阵，把周期性的量子阱结构简化为三层结构，得到了实际采用的非对称三阱结构量子阱的场分布，并讨论了量子阱结构的偏振特性。
