Abstract
Photonic transfer through elongated optical structures of submicrometre sec tion microfabricated at the surface of dielectric or semiconductor samples can be enhanced by an appropriate structuring of the local refraction index . We show from computerized simulations that both the light localization an d the spectroscopic properties of such structures can be used to selectivel y excite, in coplanar geometry, individuals molecules located in the near-f ield.
