Analytical expressions describing the propagation of surface waves for both transverse-electric and transverse-magnetic fields in semi-infinite superlattice structures are obtained. The modes are characterized by electric fields that decay exponentially in the region of lower refractive index while being oscillatory in the region of greater refractive index, and both are modulated by an envelope function that decays exponentially away from the end of the truncated superlattice. A criterion for the existence of the surface modes is developed. Numerical results are presented for several illustrative cases.
