结果表明，在折射率为抛物分布的克尔介质平板中，空间孤子的波形将进一步变陡。
The result shows that in parabolic profile slab, the form of a spatial soliton will become further steep.
介质折射率差的绝对值越大、周期数增加都使透射波谱宽度变窄。
With the increase of the periods and the absolute value of refractive index difference, the full width at half maximum of spectrum decreases.
梯度折射率或变折射率通常被用于描述非均匀介质，其折射率为点对点的变化。
The terms gradient index (GRIN) or graded index (GI) are often used to describe an inhomogeneous medium in which the refractive index varies from point to point.
