After a short historical introduction to surface electromagnetic waves (SEW) sustained by all dielectric layered structures (1DPC), the presentation will focus on their physical properties. In particular we shall review the impact of the design of the 1DPCon the quality factor of the resonances, on the propagation length and on the field localization at the 1DPC surface. Sensitivity and resolution of label-free SEW biosensors with respect to perturbations of the refractive index at the 1DPC surface will be discussed in detail. Coupling between an emitter placed in proximity of the 1DPC surface and the SEW is then discussed with particular emphasis on the emitter/1DPC distance and on the polarization. Applications of SEW in gas-sensing, biosensing, microscopy, integrated photonics, and nonlinear optics will also be reported.
