我们证明了在非线性梯度折射率（GRIN）波导中传播离轴高斯光束可以激发宽光谱范围内的光孤子。由于GRIN波导中光束尺寸和色散系数的周期性变化，这些孤子属于新发现的一类，称为导向中心孤子。在平面GRIN波导中，孤子可以同时在时域和空域进行相互作用，因此波导可以作为孤子相互作用的新平台。
We show that optical solitons in a broad spectral range can be excited by propagating an off-axis Gaussian beam in nonlinear graded-index (GRIN) waveguides. Owing to periodical variation of both the beam size and dispersion coefficient in GRIN waveguides, the solitons belong to a newly discovered class called guiding-center solitons. In planar GRIN waveguides, solitons may be arranged to interact in both the temporal and spatial domains, thus the waveguide may serve as a novel platform for soliton interactions.
