Предложен новый тип пространственно-периодической структуры - поляритонный кристалл (ПК), образованный двумерной решеткой удерживаемых двухуровневых атомов и взаимодействующих с электромагнитным полем в решетке туннельно-связанных микрорезонаторов. Основной акцент сделан на выяснении механизмов формирования когерентных поляритонов, определяемых связанными состояниями оптического поля и атомной среды для нижней ветви дисперсионной кривой поляритонов. Проанализированы случаи существенного изменения (замедления) групповой скорости оптических волновых пакетов в условиях квазиконденсации (или истинной конденсации) поляритонов. Показано, что структура ПК позволяет полностью локализовать поляритоны, что может быть использовано как для получения квазиконденсации поляритонов нижней дисперсионной ветви, так и для записи и хранения квантовой оптической информации распространяющегося светового излучения. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>фазовые переходы</kwd><kwd>пространственно-периодические среды и фотонные кристаллы</kwd><kwd>поляритоны</kwd><kwd>квантовая информация</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана грантами РФФИ ННИО_а-09-02-91350 и РТ_оми-10-02-13300, а также проектами федеральных программ Минобрнауки РФ.</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">Кеттерле B.
