We demonstrate a terahertz bandwidth silicon nanowire based radio-frequency spectrum analyzer using cross-phase modulation. We show that the device provides accurate characterization of 640Gbaud on-off-keyed data stream and demonstrate its potential for optical time-division multiplexing optimization and optical performance monitoring of ultrahigh speed signals on a silicon chip. We analyze the impact of free carrier effects on our device, and find that the efficiency of the device is not reduced by two-photon or free-carrier absorption, nor its accuracy compromised by free-carrier cross-chirp.
我们展示了一种基于太赫兹带宽硅纳米线的利用交叉相位调制的射频频谱分析仪。我们表明该器件能够对640G波特开关键控数据流进行精确表征，并证明了其在硅芯片上进行光时分复用优化和超高速信号光性能监测的潜力。我们分析了自由载流子效应对我们器件的影响，发现该器件的效率不会因双光子或自由载流子吸收而降低，其精度也不会因自由载流子交叉啁啾而受损。
