Abstract
We analyze nonlinear surface modes supported by a metal-dielectric nanostructured metamaterial with a nonlinear surface layer. We demonstrate that such a semi-infinite structure can support both TE and TM polarized surface modes with the subwavelength localization, which can be regarded as an optical analog of the electronic Tamm states. Such nonlinear Tamm states may appear even in the cases when linear surface modes do not exist.
