Cadmium mixed halide glass for optical amplification at 1.3µm

Cadmium mixed halide glass for optical amplification at 1.3µm
Cadmium mixed halide glass for optical amplification at 1.3µm
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.

Abstract

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.
