The first developments for a new integrated photonics using optical evanescent coupling from organic microstructures to fibres of hybrid nanotubes (NT) are reported. Microstructures are organic discs acting as photon reservoirs, integrated on a photonic chip fabricated by microtechnologic processes. Biomimetic peptidic/silica NT are realised by molecular self-assembly allowing centimetres long fibres of NT. Such heterostructures have been included directly on the organic as an innovative solution based on an NT in situ chip-approach. The latter allowed us to obtain an adequate evanescent coupling localised between micronic-discs and fibrous structures. Highlighted is a specific photonic propagation along various heterostructured-NT-fibres featuring distances beyond the centimetre and losses inferior to 1 dB/cm. It presents an advantageous confinement marked with strong energy localisations between NT.
