Title Optical signal amplifying triode device, optical signal transfer method using same, optical signal relay device, and optical signal storage device
Abstract The solution of the present invention is to provide an optical signal amplifying triode device (10) for directly amplifying an optical signal by using a control input light. A first input light L1 of a first wavelength &lgr;1 and a second input light L2 of a second wavelength &lgr;2 are inputted into a first optical amplifying element (26). A light of the second wavelength &lgr;2 and a third input light (control light) L3 of a third wavelength &lgr;3 outputted from the first optical amplifying element (26) are inputted into a second optical amplifying element (34). An output light L4 of the third wavelength &lgr;3 selected from the light outputted from the second optical amplifying element (34) is modulated with the intensity variation of the first input light L1 and/or the third input light L3. Therefore, the output light L4 is an amplified signal amplified with a signal amplification factor of 2 or more with respect to the third input light (control light) L3. Thus, an optical signal is directly amplified by using a control input light.
