Paper Abstract

An L-band Erbium-doped fibre amplifier consisting of a length of dual-core fibre is reported. It has a flat gain of 12.1dB from 1565nm to 1615nm with a maximum gain variation of 0.6dB, and noise figure less than 3.9dB. We have a good corroboration between the theoretical simulations and the experimental results to show that the coupling coefficient between two cores can be increased with over the wavelength range 1550 nm to 1620 nm by adjusting the core-to-core spacing and core parameters to compensate for the gain decay due to erbium alone greater than the wavelength 1550 nm.
