| Abstract: | The possibility to extend the erbium-doped fibre amplifier bandwidth from S- to L-band through all-silica erbium-doped fibres has been experimentally demonstrated. An amplifier with a parallel configuration for the S-, C- and L-bands and a double-pass scheme is proposed. The amplifier exploits the depressed-cladding fibre bending loss to obtain amplification in S-band |
