摘要：
A fiber-optic amplifier for use with optical communications systems includes a light waveguide piece for amplifying an optical input signal. A pump light source is coupled to the amplifying light waveguide piece and includes a semiconductor laser for generating pump light for the amplifying light waveguide piece. A control device regulates the wavelength of the pump light generated by the semiconductor laser to be within a desired wavelength range so that the pump light is maximally absorbed in the amplifying light waveguide piece.
