Coupled optical Tamm states localized at the edges of a photonic crystal enclosed with a nanocomposite are theoretically studied. The nanocomposite consists of nanoparticles with a dielectric core and a metal shell, which are dispersed in a transparent matrix. It is shown that the positions of the spectral peaks are sensitive to the thickness of the outermost photonic crystal layer.
