    "abstract": "Using cumulant expansion in Gaussian approximation, the internal quantum\nstatistics of damped soliton-like pulses in Kerr media are studied numerically,\nconsidering both narrow and finite bandwidth spectral pulse components. It is\nshown that the sub-Poissonian statistics can be enhanced, under certain\ncircumstances, by absorption, which damps out some destructive interferences.\nFurther, it is shown that both the photon-number correlation and the\ncorrelation of the photon-number variance between different pulse components\ncan be highly nonclassical even for an absorbing fiber. Optimum frequency\nwindows are determined in order to realize strong nonclassical behavior, which\noffers novel possibilities of using solitons in optical fibers as a source of\nnonclassically correlated light beams.",
