Abstract
We have found a new class of exact solutions for multicomponent partially c oherent solitons in photorefractive media with a drift mechanism of nonline ar response. Their novel feature is that the composite M-component sech-sha ped soliton is located on a constant-background plane wave. The solutions a re characterized by two free parameters and these are related to the maximu m intensity of the composite soliton and to the amplitude of the background . [S0031-9007(99)08778-5].
