摘要
We predict the existence of surface gap modes, known as Tamm states forelectronic systems, in truncated photonic crystals formed by two types ofdielectric rods. We investigate the energy threshold, dispersion, and modalsymmetries of the surface modes, and also demonstrate the existence andtunability of nonlinear Tamm states in binary photonic crystals with nonlinearresponse.
