ABSTRACT:
When in an optical signal amplifying triode10, light of a second wavelength λ2, selected from among light from a first optical amplifier26, into which a first input light L1of a first wavelength λ1and a second input light L2of second wavelength λ2have been input, and a third input light (control light) L3of a third wavelength λ3are input into a second optical amplifier34, an output light L4of the third wavelength λ3, selected from among the light output from the second optical amplifier34, is light that is modulated in response to the intensity variation of one or both of the first input light L1of the first wavelength λ1and the third input light L3of the third wavelength λ3and is an amplified signal, with which the signal gain with respect to the third input light (control light) L3of the third wavelength λ3is of a magnitude of 2 or more. An optical signal amplifying triode10, which can directly perform an optical signal amplification process using control input light, can thus be provided.
