Cadmium mixed halide glass for optical amplification at 1.3µm

Taylor, E.R., Samson, B.N., Hewak, D.W., Madeiros-Neto, J.A., Payne, D.N., Jordery, S., Naftaly, M. and Jha, A. (1995) Cadmium mixed halide glass for optical amplification at 1.3µm Journal of Non-Crystalline Solids, 184, pp. 61-67. (doi:10.1016/0022-3093(94)00596-6).

Record type: Article


Optical and spectroscopic data and calculations in support of an efficient 1.3µm amplifier in a Pr3+-doped cadmium mixed halide glass host are presented. It is found that the dominant parameter affecting the amplifier gain is the lifetime (325µm) of the Pr3+ 1G4 state. The long lifetime is the direct consequence of a decreased multiphonon decay rate in this low-phonon-energy glass host. Gain in excess of 30dB for 100mW pumping in low-loss fibres is predicted and for background loss of 1dB/m gain figures are as high as 15-20dB.
