中文摘要:
      利用二次谐波频率分辨光学门脉冲分析仪,从实验上研究了一阶啁啾皮秒光孤子在普通单模光纤中长距离绝热传输时脉冲波形、脉宽、啁啾的变化规律,实验结果表明,在色散较大的标准单模光纤中,一阶啁啾孤子能稳定地绝热传输一千个色散长度以上,而很好地保持双曲正割波形不变,啁啾不影响孤子的波形,但啁啾孤子的脉宽展宽速度高于非啁啾孤子绝热传输的微扰结果,采取预加重措施,可以减小孤子脉宽的增大。因此,对于占空比较小的皮秒孤子脉冲,可以不必采用复杂的消啁啾和色散管理措施,就可以利用绝热方式进行稳定传输。
英文摘要:
      The pulse profile, pulse width of the chirped picosecond soliton after long distance adiabatic transmission in standard fiber were investigated by use of SHG-FROG analyzer. It was found from the experimental results that the chirped N=1 soliton pulses could adiabatically transmit over more than one thousand dispersion length with the sech profile almost unchanged, which showed the influence of frequency chirp and fiber loss on soliton profile was little. But the broadening of soliton pulses with chirp was more than that without chirp. When the power of input pulses was more than fundamental soliton power, the broadening was slower than that at soliton power input. These results show fundamental picoseconds solitons could transmit over long distance by adiabatic mode without complex steps to remove chirp and manage dispersion.
