从理论和实验两方面研究了预啁啾对光子晶体光纤（PCF）1000 nm波段10 Gb/s传输的影响。我们使用一个24公里长的光子晶体光纤进行传输实验，其光损耗和色散分别为0.94 dB/km和-20 ps/nm/km在1064 nm。我们确认了传输后比特误码率性能的改善，即约-0.5 dB的“负功率惩罚”。我们的实验结果和理论估计表明，采用预啁啾技术和传统的Z切钛酸锂调制器可以有效地抑制色散引起的信号退化
The prechirp effect on 10-Gb/s transmission in the 1000-nm band over photonic crystal fiber (PCF) was investigated both experimentally and theoretically. We performed transmission experiments using a 24-km-long PCF whose optical loss and chromatic dispersion were 0.94 dB/km and -20 ps/nm/km at 1064 nm, respectively. We confirmed an improvement in the bit-error-rate performance after the transmission, namely a "negative power penalty" of about -0.5 dB. Our experimental result and theoretical estimation revealed that the signal degradation induced by the chromatic dispersion can be effectively suppressed by employing the prechirp technique with a conventional Z-cut lithium niobate modulator
