We report an optical link on silicon using micrometer-scale ring-resonator enhanced silicon modulators and waveguide-integrated germanium photodetectors. We show 3 Gbps operation of the link with 0.5 V modulator voltage swing and 1.0 V detector bias. The total energy consumption for such a link is estimated to be approximately 120 fJ/bit. Such a compact and low power monolithic link is an essential step towards large-scale on-chip optical interconnects for future microprocessors.
我们报道了一种基于硅的光链路，该光链路采用了微米级环形谐振器增强型硅调制器和波导集成锗光电探测器。我们展示了该链路在0.5V调制器电压摆幅和1.0V探测器偏置下实现3Gbps的运行速率。这种链路的总能量消耗估计约为120fJ/比特。这样一种紧凑且低功耗的单片链路是迈向未来微处理器大规模片上光互连的关键一步。
