| 摘 要： | 文章从描述光脉冲在光纤中传输所满足的基本方程出发,得出了展宽因子的表达式,详细研究了群速度色散对无啁啾双曲正弦高斯脉冲和啁啾双曲正弦高斯脉冲在光纤中传输特性的影响.研究结果表明,当β2C<0时,双曲正弦高斯光脉冲在传输过程中也会经历初期窄化过程,然后随着传输距离的增加而展宽;当β2 C>0时,双曲正弦高斯光脉冲的展宽因子随着传输距离的增加单调增大,这与高斯脉冲定性上是一致的,但程度不同

| Abstract: | By describing the basic equations that optical pulses must meet when transmitting in optical fiber,the essay derives the expression of the broadening factors.Furthermore,it studies the details about the influences of the group velocity dispersion on non-chirped hyperbolic sine Gaussian pulse and chirped hyperbolic sine Gaussian pulse in the optical fiber transmission.The results show that when?2C<0,hyperbolic sine Gaussian pulse will go through the primary narrowing process in the process of transmission,and then broaden with the increase of transmission distance;and when?2C>0,the broadening factors of hyperbolic sine Gaussian pulse will increase monotonically with the monotonic increase of transmission distance,which is qualitatively consistent with the Gaussian pulse,but different in degrees. |
