The field distribution of the FB modes with the transverse vector at kx = 0 (a, b) and at the resonant points 
(c,d) and 
(e,f), respectively. The longitudinal modulation period T is 1300 μm for (a–d) and 500 μm for (e,f), respectively and the other lattice parameters are the same as those in Fig. 1. The vertical dashed blue lines denote position of the refractive index peak at the input lattice surface.
