Investigation of the Propagation Length of Bloch Surface Waves on One Dimensional Photonic Crystals

Hans Peter Herzig, Gaël David Osowiecki, Nicolas Maxime André Descharmes, Babak Vosoughi Lahijani

A 1D photonic crystal structure sustaining optical surface waves is investigated. The propagation length of the surface mode is studied both using an eigenmode model and a rigorous time domain solver. The two models show good convergence. Our results demon ...
