Abstract

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>n1), and a second type of inclusion () having a refraction index n3 (n3<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 λ, and of a fundamental mode of the light in the first photonic forbidden band (BG), centred on a wavelength λ, which is different to that λof the fundamental mode guided by total internal reflection (RTI).
