The possibility of creating a polarization-sensitive absorber on the basis of the splitting of a Tamm plasmon polariton at the interface between a metallic film and an anisotropic nanocomposite layer conjugated with a photonic crystal is theoretically predicted. The effect of geometrical parameters on the optical absorption spectra under the critical coupling conditions is discussed. It is shown that, changing the polarization of the radiation falling onto the structure along its normal, one can control the absorption at the Tamm plasmon polariton wavelength.
