Abstract

In this work we focus on photonic crystal (PhC) ridges, which are composed of a dielectric ridge placed on a one-dimensional (1D) PhC, namely a periodic multilayer. In these structures, guided modes are characterized by an asymmetric light confinement, which relies on a photonic band gap (PBG) from the multilayer side and on total-internal-reflection (TIR) in all the other directions. Photonic crystal ridges are known to support guided surface waves, but here we show that at least three different guided modes can be identified, and only one of them seems to possess all the characteristics of a proper guided surface wave.
