Absorption and emission cross-section of Er3+ doped silica fibres

Barnes, W.L., Laming, R.I., Tarbox, E.J. and Morkel, P.R. (1991) Absorption and emission cross-section of Er3+ doped silica fibres IEEE Journal of Quantum Electronics, 27, (4), pp. 1004-1010. (doi:10.1109/3.83335).

Record type: Article


A detailed set of measurements is presented on determining the emission and absorption cross sections of Er3+ doped fibers for the 4 I (13/2) to 4 I (15/2) transition. Two techniques are employed: the Füchtbauer-Ladenberg analysis, based on spectroscopic data; and a more direct technique involving optical saturation of the transition. The cross sections, and in particular their ratio, are significantly different for the two techniques. Possible reasons for this are discussed, and we conclude that the Füchtbauer-Ladenberg approach is inappropriate in this situation.
