We experimentally demonstrate a spatially non-blocking five-port optical router, which is based on microring resonators tuned through the thermo-optic effect. The characteristics of the microring-resonator-based switching element are investigated to achieve balanced performances in its two output ports. The optical router is fabricated on the SOI platform using standard CMOS processing. The effective footprint of the device is about 440×660 μm2. The microring resonators have 3-dB bandwidths of larger than 0.31 nm (38 GHz), and extinction ratios of better than 21 dB for through ports and 16 dB for drop ports. Finally, 12.5 Gbps high-speed signal transmission experiments verify the routing functionality of the optical router.
我们通过实验展示了一种空间无阻塞的五端口光路由器，它基于通过热光效应调谐的微环谐振器。研究了基于微环谐振器的开关元件的特性，以在其两个输出端口实现平衡性能。该光路由器在SOI平台上采用标准CMOS工艺制造。该器件的有效占地面积约为440×660μm2。微环谐振器的3dB带宽大于0.31nm（38GHz），直通端口的消光比优于21dB，下路端口的消光比优于16dB。最后，12.5Gbps高速信号传输实验验证了光路由器的路由功能。
