We report the theoretical and experimental study of photonic propagation in organic dielectric nanotubes elaborated by a wetting template method and showing off an aspect ratio as high as 200. Single mode behaviour is theoretically demonstrated without any cut-off conditions. Efficient evanescent coupling between polymer microstructures and nanotubes dispersed on a photonic chip as well as the high confinement and propagation in a single nanotube have been demonstrated. These results show the potential of well-defined one-dimensional nanostructures as building blocks for integrated organic photonic devices. Applications such as sensing and high speed communication are envisaged. © 2011 American Institute of Physics.
