Περίληψη:
We study the existence, formation, and stability of
quasi-one-dimensional (stripes) and two-dimensional (bullets)
spatio-temporal soliton solutions for a (2 + 1)-dimensional modified
nonlinear Schrodinger equation, in the presence of the self-steepening
effect. These solutions, which are on top of a continuous-wave
background, are either dark or antidark, the latter being supported by
the self-steepening effect. We show that there exist stable
small-amplitude lump solitons, which, in the context of nonlinear
optics, constitute novel light bullets. (C) 2001 Optical Society of
