    "abstract": "We study the conditions for soliton-like wave propagation in the\nPhotorefractive (PR) and electro-optic (i.e., Pockels) material, by using\nNonlinear Schrodinger (NLS) equation. The complete NLS equation is solved\nanalytically and numerically by transforming it into the phase space. Our\nresults clearly show the existence of both the dark and bright solitary\nsolutions for the PR medium. Interestingly, however, we find only one bright\nsolitary solution in the Pockels case and there is no evidence of any dark\nsolitary solution.",
