The microstructured optical fibre comprises a core () surrounded by a sheath () comprising a base material having a refraction index (ni) and a plurality of at least two different types of inclusion: a first type of inclusion () having a refraction index n2 (n2&#x3e;n1), and a second type of inclusion () having a refraction index n3 (n3&#x3c;n1). The inclusions () are arranged and dimensioned in such a way as to ensure guidance, by total internal reflection (RTI), of a fundamental mode of the light, centred on a wavelength &#x3bb;, and of a fundamental mode of the light in the first photonic forbidden band (BG), centred on a wavelength &#x3bb;, which is different to that &#x3bb;of the fundamental mode guided by total internal reflection (RTI).

Hybrid microstructured optical fibre for guidance by means of photonic forbidden bands and by total internal reflection optimised for non-linear applications
