Abstract

A gain-flattened Er3+-doped tellurite fibre amplifier (EDTFA) with an expanded L-band is presented. The amplifier has an average gain of 28 dB and a noise figure of &lt; 6 dB with a slight gain excursion of 1 dB over a wide wavelength range of 1581–1616 nm. The total output power of the EDTFA module was 20.5 dBm and its power conversion efficiency reached 25%.
