The present invention relates to an optical fiber amplifier incorporating therein a wavelength division multiplexer and a plurality of diffraction grating pairs for generating a number of optical signals with a pumping light of one wavelength, each optical signal having a different wavelength. The optical device includes a first optical means for guiding the first pumping light and the optical signals, a second optical means for generating a second pumping light with the first pumping light and generating the plurality optical signals with the second pumping light, and an optical coupler for introducing the first pumping light into the second optical means and outputting the optical signals.
