OPTICAL FIBRE WITH A FLUORESCENT DOPANT |
摘要 |
An optical fibre including a silica-based optical core (6) for guiding most of the light waves, containing a fluorescent dopant and being surrounded by a silica-based optical sheath (5) with a lower refractive index than the core. Said core includes a central portion (2) having a radius a0 and containing said fluorescent dopant, and a peripheral portion (4) having a radius a, surrounding said central portion, having a higher refractive index than the sheath and containing no fluorescent dopant. Said core (6) further includes an intermediate portion (3) having a radius a1 and a higher softening point than said central portion (2). Said intermediate portion (3) contains no fluorescent dopant and is such that a0 < a1 < a.
