Abstract
Temperature dependence of the gain at 1.536 μm in Er3+-doped fibre are reported for 0.98 and 1.48 μm pumping. The fibre lengths at which gain is temperature insensitive are found for both pump wavelengths. The temperature insensitive gain characteristics for 0.98 μm and 1.48 μm pumping are demonstrated to fibres tuned to their temperature insensitive lengths.Keywords
