摘要
采用两次光调制技术将非归零(NRZ)码数据转换成归零(RZ)码光信号后，利用光纤参量振荡器(FOPO)结构实现了较低光功率抽运下的参量波长转换和时钟提取功能。实验表明，对于波长转换间隔为1.6 nm的10 Gbit/s时钟提取，优化的输入抽运光功率范围是8~14 dBm；当输入信号的幅度抖动和相位抖动分别大于2.28 mV和3.5 ps时，该时钟提取系统可实现抖动抑制功能，其输入/输出抖动转移曲线斜率约为0.29和0.16。
Abstract
An optical return-to-zero (RZ) signal is generated from non-return-to-zero (NRZ) signal by means of two-stage optical modulation technique, and then is launched into the fiber parametric oscillator under low power pump for parametric wavelength conversion and clock extraction. Experiments show that, for 10 Gbit/s clock extraction with 1.6 nm-interval wavelength conversion, the optimized input pump power is in the range of 8~14 dBm, the jitter suppression function can be implemented for the input signal with the amplitude and phase jitters of less than 2.28 mV and 3.5 ps, and the slopes of the corresponding input/output transfer curves are about 0.29 and 0.16, respectively.
