摘要：
We show that multimode incoherent spatial solitons are possible in logarithmically saturable nonlinear media. The mode-occupancy function associated with these soliton states is found to obey a Poisson distribution. Our analysis indicates that two approaches, i.e., the dynamic coherent density description as well as static self-consistent multimode method lead to exactly the same results. Closed form solutions are obtained for (1 + 1)D as well as for (2 + 1)D circular and elliptical incoherent solitons.
