【摘要】 利用光纤 -线性啁啾光纤光栅进行光脉冲的压缩 ,首先讨论了线性啁啾光纤光栅的色散特性 ,并给出耦合系数为反高斯函数的线性啁啾光纤光栅的色散特性 ;然后利用此种光纤光栅与正常色散光纤结合进行光脉冲的压缩 ,通过理论和数值分析 ,得出一简单设计规则 ;最后利用此规则设计一个压缩因子为 1 0的光纤 -线性啁啾光纤光栅压缩器。更多还原

【Abstract】 We demonstrated the pulse compression in optical fiber using optical fiber linearly chirped gratings. Firstly the dispersion characteristics of the optical fiber linearly chirped gratings are discussed, Secondly the simple rule is given for designing the optical fiber linearly chirped gratings to compress the optical pulse theoretically and numerically. Finally using the rule a optical fiber linearly chirped grating compressor with compression factor=10 is simulated by computers.更多还原
