论文摘要
迄今为止，尚无电气平台可实现具有较高带宽，占地面积和低功耗的设备，同时还可以实现批量生产。在这里，我们证明了使用CVD生长的石墨烯对高速石墨烯电吸附调制器的高收益制造。我们通过工程石墨烯模式重叠和设备电容来最大程度地减少大面积的石墨烯不均匀性的变化，以确保高消光比。我们使用32个石墨烯电吸附调制器制造8 mm x 1 mm芯片，并测量94％的收益率，位误差率低于7 GBITS/s的硬否决向前误差校正极限，总计为210 GBITS/s的总汇总数据速率。 Monte Carlo模拟表明，通过进一步优化设备横截面，数据速率> 0.6 TBIT/s可以触及，为基于石墨烯的超高数据速率应用铺平了道路。
To date, no electro-optic platform enables devices with high bandwidth, small footprint, and low power consumption, while also enabling mass production. Here we demonstrate high-yield fabrication of high-speed graphene electro-absorption modulators using CVD-grown graphene. We minimize variation in device performance from graphene inhomogeneity over large area by engineering graphene-mode overlap and device capacitance to ensure high extinction ratio. We fabricate an 8 mm x 1 mm chip with 32 graphene electro-absorption modulators and measure 94% yield with bit error rate below the hard-decision forward error correction limit at 7 Gbits/s, amounting to a total aggregated data rate of 210 Gbits/s. Monte Carlo simulations show that data rates > 0.6 Tbits/s are within reach by further optimizing device cross-section, paving the way for graphene-based ultra-high data rate applications.
