    "abstract": "We demonstrate a possibility to stabilize three-dimensional spatiotemporal\nsolitons (\"light bullets\") in self--focusing Kerr media by means of a\ncombination of dispersion management in the longitudinal direction (with the\ngroup-velocity dispersion alternating between positive and negative values) and\nperiodic modulation of the refractive index in one transverse direction, out of\nthe two. The analysis is based on the variational approximation (results of\ndirect three-dimensional simulations will be reported in a follow-up work). A\npredicted stability area is identified in the model\u0027s parameter space. It\nfeatures a minimum of the necessary strength of the transverse modulation of\nthe refractive index, and finite minimum and maximum values of the soliton\u0027s\nenergy. The former feature is also explained analytically.",
