We design and fabricate a four-port optical router, which is composed of eight microring-resonator-based switching elements, four optical waveguides and six waveguide crossings. The extinction ratio is about 13 dB for the through port and larger than 30 dB for the drop port. The crosstalk of the measured optical links is less than -13 dB. The average tuning power consumption is about 10.37 mW and the tuning efficiency is 5.398 mW/nm. The routing functionality and optical signal integrity are verified by transmitting a 12.5 Gb/s PRBS optical signal.
我们设计并制造了一种四端口光路由器，它由八个基于微环谐振器的开关元件、四条光波导和六个波导交叉点组成。直通端口的消光比约为13 dB，下路端口的消光比大于30 dB。所测光链路的串扰小于 -13 dB。平均调谐功耗约为10.37 mW，调谐效率为5.398 mW/nm。通过传输12.5 Gb/s的伪随机二进制序列（PRBS）光信号，验证了路由功能和光信号完整性。
