Abstract
A temperature-stabilized optical amplifier ( ) comprises at least an erbium-doped waveguide ( ) for amplifying optical signals; at least a first and a second pump sources ( ) for generating respective pump beams at a first and, respectively, a second pump wavelength (&lgr; , &lgr; ), said first and second pump wavelength being lower and, respectively, higher than 978 nm at an intermediate temperature of a predetermined range of temperature, and being subjected to drift as a consequence of temperature variations; and a pump distribution device ( ), optically coupled to said pump sources for receiving said pump beams, and optically coupled to said at least an erbium-doped waveguide for feeding to said at least an erbium-doped waveguide a mixed pump radiation comprising at least a power fraction of each of said pump beams.
