Stability of spatial soliton arrays generated in a noninstantaneous Kerr medium from partially spatiotemporally coherent light

摘要

We demonstrate numerically and experimentally how spatial soliton arrays generated through modulation instability in a planar waveguide with relaxing Kerr nonlinearity can be spatially and temporally destabilized when using a partially spatiotemporally coherent light pulse. However, the amplitude of the shot-to-shot spatial jitter is limited. This jitter depends on the correlation degree of the spatial noise between pulses, and this correlation degree strongly depends on the spatiotemporal coherence of the propagating beam.
