The propagation of light in restricted homogeneous systems of tunnel-coupled waveguides is studied. The Fourier analysis of modes at the output of the waveguide system depending on the end-excitation angle of waveguides revealed the region of excitation angles corresponding to excitation of Bragg modes. The expressions for the Bloch vector for a great number of separate waveguides are presented which describe the reflection of light in a periodic layered medium. It is shown that the Bragg diffraction of light waves in film lasers can considerably change their radiation parameters. (special issue devoted to the 90th anniversary of a.m. prokhorov)
