We report error-free long-haul transmission of optical data modulated using a silicon microring resonator electro-optic modulator with modulation rates up to 12.5 Gb/s. Using bit-error-rate and power penalty characterizations, we evaluate the performance of this device with varying modulation rates, and perform a comparative analysis using a commercial electro-optic modulator. We then experimentally measure the signal integrity degradation of the high-speed optical data with increasing propagation distances, induced chromatic dispersions, and bandwidth-distance products, showing error-free transmission for propagation distances up to 80 km. These results confirm the functional ubiquity of this silicon modulator, establishing the potential role of silicon photonic interconnects for chip-scale high-performance computing systems and memory access networks, optically-interconnected data centers, as well as high-performance telecommunication networks spanning large distances.
我们报告了使用硅微环谐振器电光调制器调制的光数据的无差错长距离传输，调制速率高达12.5 Gb/s。通过误码率和功率代价表征，我们评估了该器件在不同调制速率下的性能，并使用商用电光调制器进行了对比分析。然后，我们通过实验测量了高速光数据在传播距离增加、诱导色散和带宽-距离积增加时的信号完整性退化情况，结果表明在传播距离长达80 km时仍能实现无差错传输。这些结果证实了这种硅调制器的功能普遍性，确立了硅光子互连在芯片级高性能计算系统和内存访问网络、光互连数据中心以及跨越长距离的高性能电信网络中的潜在作用。
