Abstract

Recently, incoherent-soliton-related phenomena, such as partially incoherent spatial solitons, ¹ and modulation instability and pattern formation in spatially incoherent light beams,² have aroused many research interests in nonlinear optics. One thing in common of the these phenomena is that the material must be noninstantaneous, i.e., the material gives rise to the nonlinear refractive index depending on the optical intensity averaged over a period of time longer than the material response time.
