| 摘 要： | 本文详细分析了全内反射型光波导开关的反射特性,指出反射模存在位相变化及其相对位相差。数值计算结果表明,反射TE模和反射TM模强度反射率、反射损耗,它们的位相变化及其相对位相差都与光波导开关区介质折射率改变量、损耗以及传播角有密切关系。

| Abstract: | The reflection characteristics in total-internal-reflection waveguide optical switch are analysed in deteil. It is shown for the first time that there exists the phase changes of reflective modes and their relative phase difference. The results of numerical calculation indicate that the power reflectivity, reflective loss, phase change and their relative phase difference for the reflective TE mode and reflective TM mode remarkably depend on the refractive index change, the loss in switch region and the propagation angle. |
