| 发明名称 | Triple-sheathed monomode optical fiber | ||
| 摘要 | According to the invention, the intermediate sheath (13) is formed by assembling longitudinal elements (13A) and includes: a first optical material, the refractive index of which differs from the refractive index of the monomode core by at most 10−3; and a second optical material, the refractive index of which is lower than the refractive index of said monomode core and differs therefrom by at least 10−3. | ||

| 主权项 | 1. Monomode optical fiber comprising, from center to periphery: a monomode core doped at least partly with a rare earth, an optically inactive intermediate sheath, a multimode pumping sheath, and an outer sheath, wherein the intermediate sheath is formed by an assembly of solid bars, and said assembly of solid bars comprises first solid bars made of a first optical material with a refractive index that differs from the refractive index of said monomode core by at most 10.sup.-3, and second solid bars made of a second optical material with a refractive index that differs from the refractive index of said monomode core by at least 10.sup.-3. | ||
