中文摘要 | 理论和实验研究了基于光纤中自相位调制效应和偏移滤波的全光2R再生,实现了因放大的自发辐射噪音而恶化的数据信号的再生.数值研究了输入平均功率对信号再生的影响,结果表明,通过控制输入光纤的平均功率,Q值在5到12的40Gb/s归零码信号再生后均可实现Q值和幅度抖动的改善.最后进行了基于高非线性色散位移光纤的10Gb/s归零码ASE恶化数据信号的再生实验,误码率为10-9时标准时的再生功率代价仅为0.1dB.; All-optical 2R regeneration based on self-phase modulation in the fiber and subsequent offset filtering was investigated numerically and experimentally to restore optical data signals degraded due to amplified spontaneous emission(ASE)noise.Numerical results show that Q factor and amplitude jitter can be improved for 40 Gb/s return-to-zero(RZ)signals with Q factor between 5 and 12 when the fiber input average power is chosen suitably.The regeneration experiment on 10 Gb/s RZ ASE-degraded data signal was demonstrated using a highly-nonlinear dispersion-shifted fiber,and a power penalty of only 0.1 dB was measured at 10-9 bit-error-ratio.; 国家自然科学基金(60736036); 863专题课题(2009AA01Z256)资助 |
