| 英文摘要 | A multi-wavelength light amplifier comprises a light amplifier for amplifying a wavelength division multiplex signal with accompanying generation of spontaneous emission. An optical coupler is provided for coupling light from the light amplifier to a wavelength filter, such as Fabry-Perot filter. The filter has a plurality of spectral peaks of transmittance and corresponding valleys of reflectance, with the spectral peaks and valleys corresponding respectively to the wavelengths of the multiplex signal. The optical coupler further provides coupling of light reflected from the wavelength filter to an optical sink by which the undesired spontaneous emission is absorbed. |
