RADIATION-RESISTANT RARE-EARTH-DOPED OPTICAL FIBRE AND METHOD OF RADIATION-HARDENING A RARE-EARTH-DOPED OPTICAL FIBRE |
摘要 |
<p>The present invention relates to radiation-resistant optical fibre comprising at least one core and at least one first cladding surrounding said core. According to the invention, said core comprises a phosphosilicate matrix, said core being rare-earth doped, the rare earth being chosen from erbium, ytterbium, neodymium, thulium or erbium-ytterbium or thulium-holmium codoped and said core is cerium codoped. The invention also relates to a method for radiation-hardening an optical fibre comprising the core having a phosphosilicate matrix, said core being rare-earth doped, the earth being chosen from erbium, ytterbium, neodymium and thulium, or erbium-ytterbium or thulium-holmium codoped, and including a step of cerium codoping the core of said fibre.</p> |
