We demonstrate an optical hitless bypass switch based on nanomechanical proximity perturbation for high-bitrate transparent networks. Embedded in a single-level pi-imbalanced Mach-Zehnder interferometer, the two nanomechanical-based Deltabeta-directional couplers permit broadband signal rerouting on-chip, while the selected wavelength remains unaffected at all times for optical filter reconfiguration. The optical hitless switch is implemented in the silicon nanophotonics platform, with experimental measurements matching well with numerical and theoretical modeling.
我们展示了一种基于纳米机械近场扰动的光无冲击旁路开关，用于高比特率透明网络。嵌入单级π不平衡马赫-曾德尔干涉仪中的两个基于纳米机械的Δβ定向耦合器允许片上宽带信号重新路由，而在光滤波器重新配置时，所选波长始终不受影响。该光无冲击开关在硅纳米光子学平台上实现，实验测量结果与数值和理论模型匹配良好。
