Abstract
The authors report the realisation of a contradirectional EDFA whose 1480 nm pump beam, generated by a DFB laser diode, is recycled in it by a photoinduced intracore fibre Bragg grating. Insertion of the fibre grating does not introduce any extra input coupling loss and, for the same gain and noise figure values, allows a 20% decrease of the pump power compared to the EDFA without a fibre grating
