摘要
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.
