Abstract: PROBLEM TO BE SOLVED: To adjust the optical power of a signal of each wavelength subjected to wavelength multiplexing, and to adjust the optical output power of each wavelength and deviation between wavelengths. SOLUTION: At an optical power adjustment section 8, an optical star coupler 18 branches light, and optical filters 20a, 20b, and 20c extract the light of wavelengths λ1, λ2, and λ3 from each branched light. Then, optical gain adjustors 17a and 17b amplify or attenuate merely the light of the wavelength λ2 and that of wavelength λ3 independently. After that, an optical start coupler 19 put together the light of each wavelength. At an optical amplification section 9, the entire portion of the resultant light is amplified. A control apparatus 14 controls the gain of the optical amplification section 9 and the optical gain adjusters 17a and 17b individually.
