Laming, R.I., Townsend, J.E., Payne, D.N., Meli, F., Grasso, G. and Tarbox, E.J. (1991) High-power erbium-doped-fibre amplifiers operating in the saturated regime IEEE Photonics Technology Letters, 3, (3), pp. 253-255. (doi:10.1109/68.79772).

Record type: Article


Highly saturated, erbium-doped fiber amplifiers can be employed as efficient power amplifiers. Differential pump-to-signal conversion efficiencies of 59%. (quantum efficiency of 93%) can be obtained, resulting in 54 mW (+17.3 dBm) of amplified signal for only 100 mW of pump power at 978 nm. In addition, these amplifiers are shown to have virtually-flat spectral-gain characteristics with a 1 dB bandwidth in excess of 38 nm.
