| 摘 要： | 文章研究了构成光纤环的色散渐减光纤三阶色散分别为正、负以及忽略三阶色散情况下,超短脉冲在光纤环中的传输特性,通过比较发现脉冲内拉曼散射与负的三阶色散相互作用更有利于飞秒脉冲的传输与压缩,从而使飞秒光脉冲在环形腔中的传输特性得到极大改善。

| Abstract: | The quality of femtosecond optical solitons reshap ing in a nonlinear loop mirror will degenerate due to the third-order dispersion and high order nonlinear effectives. The characteristics of ultrashort pulse transmission in a non-linear optical loop mirror have been investigated. The results show that the loop constructed with negative third-orderdispersion can significantly improve the transmission characteristics of femtosecond optical solitons. |

| Keywords: | ultra-short pulse nonlinear optical loop mirror negative third-order dispersion optical switching |
