The application of Ga:La:S-based glasses for optical amplification at 1.3µm

Madeiros-Neto, J.A., Wang, J., Samson, B.N., Dussardier, B., Hewak, D.W., Taylor, E.R., Laming, R.I. and Payne, D.N. (1994) The application of Ga:La:S-based glasses for optical amplification at 1.3µm At 9th International Symposium on Non-Oxide Glasses, China. 10 - 14 May 1994.

Record type: Conference or Workshop Item (Paper)


The optical properties of praseodymium-doped low-phonon energy glasses have recently attracted considerable attention for their potential application as a 1.3µm Pr3+-doped optical fibre amplifier. Sulphide glasses based on Ga2S3 and La2S3 are amongst the lowest phonon energy glass which are suitable for this application, with quantum efficiencies exceeding 50% currently measured on bulk samples in our laboratory. The purpose of this paper is to describe the thermal, optical and spectroscopic properties of Pr3+-doped sulphide based glasses and report on progress to date in achievement of a Pr3+-doped sulphide based fibre.
