Profile of photorefractive one-dimensional bright spatial solitons.
Analytic solutions for the profile of one-dimensional bright photorefractive steady-state spatial solitons generated as a result of screening of drift or photogalvanic currents are found by means of a power series development. The solutions are valid over all ranges of intensities. We also give simple analytic expressions that describe the soliton full width at half-maximum as a function of all important experimental parameters.
