A system of equations of Maxwell-Duffing type and describing forward- and backward-propagating waves in such a grating, is derived. Exact solitary wave solutions are found, analyzed, and compared with the results of direct numerical simulations.23 pages, 8 pictures. Accepted for publication in a book "Dissipative Solitons" (Ed.
