Yb3+ sensitised Er3+-doped silica optical fibre with ultrahigh transfer efficiency and gain

Yb3+ sensitised Er3+-doped silica optical fibre with ultrahigh transfer efficiency and gain
Yb3+ sensitised Er3+-doped silica optical fibre with ultrahigh transfer efficiency and gain
Efficient 1.54µm emission under 1064nm excitation of Er3+:Yb3+ codoped silica fibre is reported. The energy transfer efficiency from Yb3+ to Er3+, ~95% even under high inversion, is comparable to that in multicomponent glass fibres. The small signal gain of ~45dB is measured and power amplifiers with 145mW output power demonstrated.

Abstract

Efficient 1.54µm emission under 1064nm excitation of Er3+:Yb3+ codoped silica fibre is reported. The energy transfer efficiency from Yb3+ to Er3+, ~95% even under high inversion, is comparable to that in multicomponent glass fibres. The small signal gain of ~45dB is measured and power amplifiers with 145mW output power demonstrated.
