标题： Intensity Distribution of Modes in Surface Corrugated Waveguides

摘要： 在表面随机起伏的光波导中，给出了传输和反射系数的精确计算。 随着波导起伏部分长度的增加，通过最低模式的前向耦合具有强烈偏好。 预测了增强后向散射随波长变化的振荡行为。 尽管传输强烈各向异性，但对透射波的概率分布的分析确认了在此配置下由随机矩阵理论预测的体 disorder 分布。 显示英文摘要

摘要： Exact calculations of transmission and reflection coefficients in surface randomly corrugated optical waveguides are presented. As the length of the corrugated part of the waveguide increases, there is a strong preference to forward coupling through the lowest mode. An oscillating behavior of the enhanced backscattering as a function of the wavelength is predicted. Although the transport is strongly non isotropic, the analysis of the probability distributions of the transmitted waves confirms in this configuration distributions predicted by Random Matrix Theory for volume disorder.
