我们展示了硅有机混合（SOH）电光调制器，使正交相移键控（QPSK）和16状态正交幅度调制（16 QAM）具有高信号质量和创纪录的低能耗。SOH集成将高效的电光有机材料与传统的绝缘体上硅（SOI）槽波导相结合，并且允许克服硅作为光学集成平台的固有限制。我们演示了QPSK和16 QAM信号在28 GBd的符号速率与峰峰值驱动电压为0.6 V-pp。对于112 Gbit/s的16 QAM实验，我们测量到5.1 x 10（-5）的误码率和仅19 fJ/bit的创纪录低能耗。(C)2014年美国光学学会
We demonstrate silicon-organic hybrid (SOH) electro-optic modulators that enable quadrature phase-shift keying (QPSK) and 16-state quadrature amplitude modulation (16QAM) with high signal quality and record-low energy consumption. SOH integration combines highly efficient electro-optic organic materials with conventional silicon-on-insulator (SOI) slot waveguides, and allows to overcome the intrinsic limitations of silicon as an optical integration platform. We demonstrate QPSK and 16QAM signaling at symbol rates of 28 GBd with peak-to-peak drive voltages of 0.6 V-pp. For the 16QAM experiment at 112 Gbit/s, we measure a bit error ratio of 5.1 x 10(-5) and a record-low energy consumption of only 19 fJ/bit.
