Abstract
By doping the core of a triplex quartz optical fibre with P2O5, GeO2, and B2O3, it is possible to reduce its temperature sensitivity (TS) from 7·10−6K−1 to (4–5)·10−6K−1. The same decrease in TS can be obtained by doping the third layer with TiO2. The doping level in both cases should be 30–40 mole%. The TS of an optical fibre greater than 80 μm in diameter is almost not a function of random changes in the diameter. For a liquid-crystalline polymer cladding above a fixed value, the TS of the fibre is weakly dependent on the change in the thickness.
