The calculation was carried out for the physical parameters of a semiconductor structure with quantum-well effects in the presence of resonant nonlinearity and intraband relaxation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нелинейная динамика</kwd><kwd>резонансная оптика</kwd><kwd>коллективные эффекты излучения</kwd><kwd>суперкристаллы квантовых точек</kwd><kwd>диполь-дипольное взаимодействие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nonlinear dynamics</kwd><kwd>resonant optics</kwd><kwd>collective effects of radiation</kwd><kwd>quantum dots supercrystals</kwd><kwd>dipole-dipole interaction</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">Alù, A.
