Изучаются условия возникновения таких устойчивых пространственно-неоднородных структур световой волны генератора оптического излучения. Образование неоднородных структур, которые возникают в плоскости, ортогональной направлению распространения волны, обеспечивается тонким слоем нелинейной среды и контуром двумерной запаздывающей обратной связи с оператором поворота пространственных координат световой волны в плоскости излучения оптического генератора. В пространстве основных параметров генератора (управляющий параметр, угол поворота пространственных координат, величина запаздывания) построены области генерации устойчивых пространственно-неоднородных структур, был проведен анализ механизмов их возникновения.</p></abstract><trans-abstract xml:lang="en"><p>A model of distributed information carriers in the form of stable spatially inhomogeneous structures in optical and fiber-optic communication systems is considered. We study the conditions for the occurrence of such stable spatially inhomogeneous structures of the light wave of the generator of optical radiation. The formation of inhomogeneous structures that occur in a plane orthogonal to the direction of wave propagation is provided by a thin layer of nonlinear medium and a two-dimensional lagging feedback loop with the rotation operator of the spatial coordinates of the light wave in the emission plane of the optical generator. In the space of the main parameters of the generator (a control parameter, the angle of rotation of the spatial coordinates, the magnitude of the delay), the areas of generation of stable spatially inhomogeneous structures are constructed, the mechanisms of their occurrence are analyzed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пространственно-неоднородные волны</kwd><kwd>бифуркация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spatially inhomogeneous waves</kwd><kwd>bifurcation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ахманов С.
