Abstract
An optical amplifier waveguide provides variable amplification gain to a broad wavelength input signal. The degree of amplification is proportional to the length of the transmission of the input signal along the amplification waveguide. The amplification waveguide means further comprises a series of output wavelength couplers, which are preferably fiber gratings, placed along the length of the amplification waveguide for coupling a predetermined amplified signal from the amplification waveguide to the output fiber. Additionally, the optical amplifier waveguide of the present invention may include a plurality of noise wavelength coupling means, which are preferably fiber gratings, for coupling unwanted noise from the amplification waveguide means to a noise dissipation means.
