| Abstract: | Temperature dependence of the gain at 1.536 mu m in Er/sup 3+/-doped fibre are reported for 0.98 and 1.48 mu m pumping. The fibre lengths at which gain is temperature insensitive are found for both pump wavelengths. The temperature insensitive gain characteristics for 0.98 mu m and 1.48 mu m pumping are demonstrated to fibres tuned to their temperature insensitive lengths.<> |
