Fig. 1

a, b Schemes of Bragg mirror in the case of different alternating orders of n 1 and n 2 layers. c Schematic illustration of modes existing in 1D PhC terminated by a periodically profiled metal film in p-polarization for various diffraction orders: 0 (solid lines), “ −1” (dotted lines) and “ +1” (dashed lines). Blue lines correspond to the dispersion of SPP, red lines – guided modes and black dash-dotted line – defect mode. RI = 1, n 1, n 2 mark light lines in media with corresponding refractive indices. Vertical dotted lines correspond to first and second Brillouin zones (BZ)
