Abstract
Abstract The efficiency, small signal gain spectrum and noise characteristics of erbium-doped fluorozirconate fibre amplifier with a core diameter of 2.8 μm and a core-cladding refractive index difference of 40×10 −3 are described. A gain coefficient of 3.4 dB/mW for 1.488 μm pumping is obtained. Gain saturation occurs at 7 mW injected pump power. A gain of 27 dB obtained with 14 mW injected pump power gives an efficiency coefficient of 1.9 dB/mW in the gain saturation region.
