摘要：The present invention relates to an optical fiber amplifier incorporating therein

a wavelength division multiplexer and a plurality of diffraction grating pairs forgenerating a number of optical signals with a pumping light of one wavelength, eachoptical signal having a different wavelength. The optical device includes a first opticalmeans for guiding the first pumping light and the optical signals, a second optical meansfor generating a second pumping light with the first pumping light and generating theplurality optical signals with the second pumping light, and an optical coupler forintroducing the first pumping light into the second optical means and outputting theoptical signals.
