В работе рассматривается математическая модель генератора оптического излучения с контуром нелинейной запаздывающей обратной связи и оператором растяжения (сжатия) пространственных координат световой волны в плоскости, ортогональной направлению излучения. Показано, что наличие запаздывания в контуре обратной связи может привести к генерации устойчивых периодических пространственно-неоднородных колебаний. В пространстве основных параметров генератора построены области генерации устойчивых пространственно-неоднородных колебаний, изучен механизм их возникновения, построены приближенные асимптотические формулы.</p></abstract><trans-abstract xml:lang="en"><p>Spatially inhomogeneous structures of light waves are used as a mechanism of compacting information in optical and fiber-optic communication systems. In this paper, we consider a mathematical model of an optical radiation generator with a nonlinear delayed feedback loop and a stretching (compression) operator of the spatial coordinates of the light wave in a plane orthogonal to the radiation direction. It is shown that the presence of a delay in the feedback loop can lead to the generation of stable periodic spatially inhomogeneous oscillations. In the space of the main parameters of the generator, the spaces of generation of stable spatially non-uniform oscillations are constructed, the mechanism of their occurrence is studied, and approximate asymptotic formulas are constructed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пространственно-неоднородные волны</kwd><kwd>бифуркация</kwd><kwd>оптические системы передачи информации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spatially inhomogeneous waves</kwd><kwd>bifurcation</kwd><kwd>optical information transmission systems</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">РФФИ, проект № 19-31-90133.</funding-statement><funding-statement xml:lang="en">RFBR, project No 19-31-90133.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">S.
