| 摘 要： | 利用全内反射和波导理论，分析了多模波导反射区全内反射(Total Internal Reflection，TIR)型光开关的物理模型和降低串音和损耗的原因，给出改进Y分叉全内反射型光开关特征的近似计算方法。数值模拟表明，扩展多模波导的Y分叉全内反射开关的串音和损耗可分别下降15．5dB和0．65dB以上。

| Abstract: | The reason that multimode waveguide of total internal reflection (TIR) based Y-branch switch has less cross-talk and less loss are analyzed by utilizing waveguide theory. A physical model of TIR is given and an approximate calculation method of improved TIR Y-branch switch is obtained. Simulation shows that the cross-talk and loss of the multimode waveguide of TIR Y-branch switch decrease by 15.5 dB and 0.65 dB respectively. |
