We present a 4x4 spatially non-blocking Mach-Zehnder based silicon optical switch fabricated using processes fully compatible with standard CMOS. We successfully demonstrate operation in all 9 unique switch states and 12 possible I/O routing configurations, with worst-case cross-talk levels lower than -9 dB, and common spectral bandwidth of 7 nm. High-speed 40 Gbps data transmission experiments verify optical data integrity for all input-output channels.
我们展示了一种基于马赫曾德尔干涉仪的4x4空间非阻塞硅光开关，该开关采用与标准CMOS完全兼容的工艺制造。我们成功演示了其在所有9种独特开关状态和12种可能的输入/输出路由配置下的运行情况，最坏情况下的串扰水平低于-9 dB，共同光谱带宽为7 nm。高速40 Gbps数据传输实验验证了所有输入-输出通道的光数据完整性。
