We report the first demonstration of soliton self-frequency shift (SSFS) controlled by a weak continuous-wave (CW) laser, from a tellurite photonic crystal fiber pumped by a 1560 nm femtosecond fiber laser. The control of SSFS is performed by the cross-gain modulation of the 1560 nm femtosecond laser. By varying the input power of the weak CW laser (1560 nm) from 0 to 1.17 mW, the soliton generated in the tellurite photonic crystal fiber blue shifts from 1935 to 1591 nm. The dependence of the soliton wavelength on the operation wavelength of the weak CW laser is also measured. The results show the CW laser with a wavelength tunable range of 1530-1592 nm can be used to control the SSFS generation.
我们首次展示了通过弱连续波（CW）激光控制孤子自频移（SSFS）的实验，该实验使用掺碲酸盐光子晶体光纤作为增益光纤，由 1560nm 的飞秒光纤激光器泵浦。通过 1560nm 飞秒激光的交叉增益调制实现 SSFS 的控制。通过改变弱 CW 激光（1560nm）的输入功率从 0 到 1.17mW，在掺碲酸盐光子晶体光纤中产生的孤子从 1935nm 蓝移到 1591nm。同时还测量了孤子波长对弱 CW 激光工作波长的依赖关系。结果表明，波长可调范围为 1530-1592nm 的 CW 激光可用于控制 SSFS 的产生。
