摘要： The invention relates to optical fibres provided with cavities in the structure thereof. The inventive optical fibre comprises a central core (1), a first annular area (ra) encompassing said central core (1), a second annular area (rb) encompassing the first annular area (ra) and containing average size cavities (3) whose cross section is strictly ranges between a first specified threshold and a second specified threshold strictly greater than the first threshold, a third annular area (rc) encompassing the second annular area (rb) and containing large size cavities (4) whose cross section is strictly greater than the second threshold. In the cross section of the optical fibre, each beam coming away from the core centre outwards the optical fibre meets at least the average size cavity (3) of the second annular area (rb) or the large size cavity (4) of the third annular area (rc), wherein the mean distance between the external perimeter (Ca) of the second annular area (rb) and the internal perimeter (Cb) of the third annular area (rc) is less than half the mean dimension of the large size cavity (4).

摘要： The invention concerns a cladding-pumped optical fibre comprising: a core with optical index n1, around the core, a first cladding with index n2 less than n1, around the first cladding, a second cladding with index n3 less than n2. The interface between the first and second claddings has, in cross-section, a substantially polygonal shape. The invention also concerns a method for making a cladding-pumped optical fibre, which consists in executing the following steps: positioning, around a central optical preform comprising a core with index n1 enclosed with a first cladding with index n2 less than n1, several bars with index n3 less than n2, vacuum drawing of the optical preform and the bars, until fibre drawing and an optical fibre comprising a core and two claddings are obtained.

摘要： The invention relates to an optical fibre with a multmode core (10) consisting of: a first uniform zone (11) comprising a first material having a first index of refraction; and a second zone (12) comprising at least a second material having a second index of refraction which is lower than the first, said second zone (12) being disposed on the periphery of the first zone (11). The aforementioned first and second zones are configured so that the interface therebetween defines a star-shaped contour in the transverse plane, such that the multimode transmission characteristics of the fibre are identical to those of a graded index fibre. The invention is suitable for amplifier fibres, dual-core lasers or transmission fibres for local networks.
