摘要： A monomode optical fibre provided for transporting light having a wavelength comprised between 480 and 550 nm. The fibre comprises a core made of a first transparent dielectric material having a first refractive index nc and a substantially circular cross-section with a radius dimension a. The fibre further comprises a first cladding coaxially applied on said core and made of a second transparent dielectric material having a second refractive index nm1 inferior to nc. The first transparent dielectric material consists in substantially pure silica, the second transparent dielectric material consists in doped silica, the thickness of the first cladding is comprised in a range of 5 to 15 microns and the values of nc and nm1 are choosen in such a manner that the numerical aperture is less than 0.1 and the radius dimension a is above 2 microns.
