本文研究了在高非线性碲酸盐光子晶体光纤中利用克尔效应实现群速度色散的全光控制。当抽运峰值功率从1.56 μm提高到11.6kW时，利用孤子自频移抵消法测得零色散波长的红移超过307 nm。GVD的全光控制不仅为构建全光控制光子器件提供了一个新的平台，而且为非线性光纤光学和光-物质相互作用提供了一个新的实验平台。
We demonstrate all-optical control of group velocity dispersion (GVD) via optical Kerr effect in highly nonlinear tellurite photonic crystal fibers. The redshift of the zero-dispersion wavelength is over 307 nm, measured by soliton self-frequency shift cancellation, when the pump peak power of a 1.56 μm femtosecond fiber laser is increased to 11.6 kW. The all-optical control of GVD not only offers a new platform for constructing all-optical-control photonic devices but also promises a new class of experiments in nonlinear fiber optics and light-matter interactions.
