Prediction of light localization. a–c Electric field amplitude |E z | of modes in 2-cohesively (a), 6-cohesively (b) and 14-cohesively (c) bonded stacks of silk filaments (with nanofibrillar structures) at the wavelengths marked by the larger circles in f. The inner boundaries of sericin layers are marked by the coloured lines. d, e Norms of the Fourier transform of the electric field E z of a, c, respectively. f Q factors of adjacent 20 modes around λ0 = 600 nm. The green, blue and red dots correspond to the 2-filament, 6-filament and 14-filament structures, respectively
