通过实验研究了光孤子源的产生及光纤孤子的传输。采用增益开关分布反馈半导体激光器作为超短脉冲源，用１．４８μｍ激光泵浦的掺饵光纤放大器作为第一级功放，用Ｆ－Ｐ腔谱窗降啁啾技术产生变换限制脉冲，用另一只１．４８μｍ激光泵浦掺饵光纤放大器作为第二级功放，得到了重复频率为２．５ＧＨｚ的高功率变换限制光孤子脉冲；进行了３０ｋｍ光孤子传输实验，观察了光孤子的传输特性与高阶孤子的压缩特性。
The generation of optical soliton sources and the transmission of optical fiber solitons are studied experimentally. A gain switching distributed feedback semiconductor laser is used as an ultrashort pulse source. A 1.48μm laser-pumped erbium-doped fiber amplifier is used as a first stage power amplifier. A transform limiting pulse is generated by an F-P cavity window chirp technique, Only 1.48μm laser-pumped optical fiber amplifier is used as the second-stage power amplifier to obtain the high power conversion-limited optical soliton pulse with the repetition frequency of 2.5GHz. The experiment of 30km optical soliton transmission is carried out and the propagation characteristics of optical soliton and Compression properties of higher order solitons.
