摘要

The microstructured optical fibre comprises a core (4) surrounded by a sheath (1) 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 (2) having a refraction index n2 (n2 n1), and a second type of inclusion (3) having a refraction index n3 (n3n1). The inclusions (2, 3) 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 λRTι, and of a fundamental mode of the light in the first photonic forbidden band (BG1), centred on a wavelength λBG1, which is different to that λRτι of the fundamental mode guided by total internal reflection (RTI).
